There is already a word for “reverse degrowth.” That word is “growth.” (Or “grow,” possibly “regrow” in your context.)

I have not much else to add other than I am continuing to post on Lemmy regardless of whether or not it becomes popular. I’m pretty much the only voice in the two communities I’m most active in, and if that winds up with me just shouting into the void about topics I like, well… I’ll still do it, because t that’s what I enjoy doing. Maybe some day, maybe not. Fuck it.
