Is this like..... "no way to share your comics instantly?" (i.e., internet and friends?) Or is this a hypothetical in which it is impossible to someday publish, print, or even just hand out a hand-stapled zine at a craft fair?
Because if it's just a lack of immediate sharing options, I think I would still be striving to make my stories into comics that could one day be published and shared. Whether I would've gotten this far or not, I have no idea, but the idea of making a webcomic didn't even occur to me until college, and I've aspired to tell stories and make comics well before then.
If it's, instead, a knowledge that nothing I make will ever see the light of day, that's harder to say. I think I would absolutely still create, because there's something about the act of creation that's different from just knowing a story in your mind. But it would likely be scattered over the pages of a sketchbook instead of organised and coherent. I'd be building the story and all of the moments I wanted and bringing them into being, but I might not feel as much of a need to make a "final" version that's all in the right order.
