It isn't really that odd, considering you've only been here a couple of weeks. Mutual Aid is a foundational idea in most if not all anarchist projects and theory.
There may be many scammers, yes, but the goal remains the same - get help to those who need it from those in a position to give it.
As for being part of the problem, I must disagree. Scammers aren't leeching just this, they'd be present in any system purporting to help others (in gov't systems this is called fraud), the goal of these grassroots aid projects is to help those who fall through the cracks of more formalized systems and decentralize some aid in case the church/NGO/gov't can't or won't help (see the Hurricane Helene/Katrina responses when FEMA is overwhelmed).
Means-testing recipients is kinda a dick move anyway: those who have demonstrable need will have a harder time getting aid and time/money that should be spent helping are now spent with verification.
No? They don't hoard dollars, they hoard deeds if anything. Should the bottom fall out of the American Market, they'll just pack it up and go to China or Russia or Europe. Their holdings won't lose value over time, and anything short of super steep taxes on unrealized gains or nationalization won't really affect them.
Those won't happen because it'll catch up the petty bourgeoise in the thresher, and common Americans won't stand for that.
What would prevent the same happening in the next wave of rats jumping ship? They don't know anything about the servers or their niches, so they pick whatever. Listing all the servers and their missions is a good start for those motivated to join, but for those more on the fence, how do we ease the transition?
Only in the professional sense, medicine and engineering as concepts of let's not have these people die of what we know to be preventable has been around a lot longer than agriculture.
