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.
I was under the impression that not only has this been the (German) law for decades, it used to be the only legal way of installing spyware and also exfiltrating data. But I can’t be assed to look it up.
