I think also it really really depends on the story format of the comic that you're making. People who create long-form comics as opposed to episodic one-offs are probably more inclined to try create things for print because graphic novels are still alive and well as an industry.
The floppy comic (the weekly type you see Marvel and DC putting out still) are actually a dying breed, and the information I've been getting lately is that those two publishers are just breaking even with them and for the most part make their money through the movies. My friend (he's a published artist in the industry, btw, this isn't necessarily some random chitchat we were having haha) speculates that some of why they continue putting out floppies despite much smaller returns has something to do with just keeping properties alive, but I really don't have authority to expand on that, just to relay what he said.
But the graphic novel industry? Alive and well. And growing!
The comic i'm working on currently (no link, it's not up on tapastic yet) is long-form and I'm approaching it with the intention of printing it eventually. Part of it is that, yes, this is the way that we're used to reading comics for the most part. I think another part of it is that the act of printing a piece of digital art work actually kind of changes your perspective on it in a really interesting way.
I've worked in the games industry for the past 3 years as an illustrator/concept artist/animator, so for the most part my stuff is digital and never leaves that medium. Like @jessicasurline said, digital feels really ephemeral. Not only does it feel like it can disappear (which OP seems to be okay with, and that's perfectly fine!) but sometimes there's a tendency for it to not really register as a real thing. When you have stuff printed out, there's this feeling of solidity to it. It is thing. You are holding a thing you created in your hands and you can touch it and it exists. And having a whole BOOK of this thing you worked really hard on as an easy-to-understand measurement of the effort you put in. It's kind of cool.
I have a friend who has a hard time motivating themselves to work on a comic they've been working on steadily, and one of their biggest pieces of advice was to print it out. One of the best ways to motivate yourself is to print your stuff out, even if it's just on printer paper. Kind of just reminds you of what you've already done so far a little more than just scrolling through pages you've made does.
Of course, this is all a very specific perspective! I actually find it really cool that some people approach these things differently, it means that the medium for storytelling is expanding. All really interesting to read.
