Yeah, that's true. I've played around a bit with photoshop, but it doesn't feel as good as drawing ink on the page. Even though I hate making mistakes, if I could just keep deleting them, I feel like my drawing progress might be hindered because of it. Whenever I make a mistake that I can't reverse, I'm more likely to "internalize" it and remember it for next time to avoid making the same mistake in the future, whereas, if I could easily delete it, then it won't really matter how many mistakes I make as long as I can make "one good stroke". I really love Steemit because every time I post the progression of one of my art pieces, it's a way to chronicle every step. Since it's on blockchain, it will stay there unchanged. I feel like Steemit really suits my strict nature when it comes to precision and preservation.
