Unfortunately I feel this is still a slippery slope and one that also even AES haven’t been very good at handling. Who decides what is “some way of contributing”? Is community work, emotional support, spreading knowledge about a hobby, some form of art a “valid” way to “earn one’s living”? And how much of those you would have to do? What happens if you are hindered? Who decides?
I think without a post-scarcity (or severely degrowth) economy, these will stay hard to find a common ground on.
It’s such a great litmus test for any historical figure to just go to their Wikipedia page and look how many wifes and children they had and what ages the wifes were at marriage.
