For me personally its the bulk that comes with it, all the materials and space needed for things
meanwhile, with digital, its all in the funny beep boop machine.
Also always missed all the nice little helper tools you get with digital stuff like undo, layers, etc

I kinda also had a hard time developing the skills for IRL drawing, but thats more a personal thing
hope this is somewhat helpful

Oh gosh sooooo many things!
Cost, space, stress...it's a lot of factors
I haven't really properly drawn traditionally since I was in highschool, especially using a sketchbook. Which is something I'd like to get back into doing but there's just a huge roadblock for me there mentally. Every time I try to I just can't!

I also feel like the fact that my skills don't transfer over very well is also frustrating. My art might look "good" when I'm doing digital but it doesn't traditional ( of course due to lack of practice haha )

My lack of skill, generally. With digital art, you have a lot more leeway to correct mistakes and adjust colors after a piece is finished. Physical mediums have a lot more finality, which is intimidating. There's also so many different mediums and its a lot less accessible to learn, because you not only have to take techniques into account, but also which materials are good (easy to work with, good pigment, etc) and which ones suck. Budget is also a large concern, as cheap materials tend to be hard to work with, which can be discouraging.

It's the cost really.

The constant purchasing of materials for drawing with and drawing on ramps up quick, while on the other side I can do a one time purchase of 100 bucks on a tablet and be good for years as well as a one time license on CSP and be good indefinitely!

No constant heading out burning gas and burning my car to spend money on supplies, if I want to I can but usually its just too expensive.

doesn't stop me from doodling on paper any chance I get though!

Money. Working with cheap materials means getting good with cheap materials. So the only way to have good quality work is to cough up the dough.

Also to stay competitive in the art industry means having a strong proficiency with digital art programs. So I guess most of the reasons I default to digital are practical. Otherwise traditional art feels more fulfilling to me.

Like many have said, cost. Its a lot of personal pressure to make something beautiful with anything I have even though I do enjoy drawing with pen and paper. I'd rather use dollar pens and printer paper, I have nice sketchbooks and a few nice pens I've been gifted very kindly that sit half full because of anxiety about not being good enough.. and I don't want to get too good with them because I can't afford to replace them when they're dead

definitely the cost. i want to try all the things but all the things cost so much money i do not have.

Gonna see how much I can hurt you in as few words as possible,

"I'm a digitalist."

I’m already a traditional artist so this isn’t for me, but I just wanted to say this is a cool idea! I hope it goes well!
I think there’s a mentality that you just can’t use cheaper materials and need to spend on more expensive ones and that’s a shame. A lot of cheaper ones are just as good if not better. Heck I still use crayola pencils for a lot of stuff. There’s a few great channels on YouTube that showcase that more money doesn’t always mean better.

I love your paintings and that you use reclaimed wood and recycled paper for some of them. And you really show the top tier work you can do with those!

I get executive dysfunction about the setup, even though I used to carry a sketchbook everywhere, it's so much easier on my brain to open up something on my tablet and get going on that

I think the first thing is unfortunately how it performs. I've found on average it doesn't get liked as much, which is fine but it's sad that influences is me so much!

Additionally I don't have a scanner, so I can't get the images looking just right.

End of the day my heart lies in traditional art, I would love to do watercolor more, but people don't commission that, so I stopped offering it as an option. I don't have all the time to do art for myself anymore. But maybe I should just buckle down and do it more!

The only thing “stopping” me is that I need to get used to making mistakes and not being able to correct them, but all in all I love traditional art more than digital one

Physical materials needed to be bought, the space it takes up to do the art, and the fact that there is no "undo" button. I started out traditional and then moved to mostly digital. I still do pencil sketches that I then digitize afterwards.
I'm also intimidated by painting traditionally, I'm very uninformed with color theory and blending, and a lot of times I've tried painting with acrylics or watercolors, they get muddy. :(

cost of materials mostly. my mistakes waste money. i'm experimenting with traditional media anyway but it feels bad to know that my flops are basically eating away at my ability to keep experimenting in the medium unless i go buy more materials. also it does feel bad that most of my skills as a digital artist won't transfer, i'm basically starting from scratch.
