It seems to me the current choices, dictated by culture, capital, and economics, are a) grow or b) decline.
Is a steady state possible? Can a cobbler, independent farmer, carpet cleaning service, or whatever, do their thing for 40+ years?
I don't know.
Certainly not if they accept outside investment capital, where the lender is expecting an ever greater return on their investment.
Certainly not if when there are predators. eg "Your margin is my opportunity" -- Jeff Bezos
Certainly not if your gig is mooted by technological progress.
Examples of successful steady state ventures would help me (us) think through these issues. But I'm struggling to think of some. Residential plumber (and similar trades)? Automobile mechanic?
