As it stands now, this community serves mostly as a way to get money. That isn't a bad thing, but cash is not a 1-size-fits-all solution to every problem. Taking care of a persons needs is always priority #1, but at times, said person is unfit to handle money in a way that reliably alleviates those needs. Traditional, local, mutual-aid networks can usually address this in the form of community pot lucks, clothing exchange, etc. Here we are more or less limited to advice and more money.
Making a rule about unsolicited advice and being critical of users, limits us to just money as a tool to solve problems. Sometimes people need a tough conversation to grow as a person, sometimes people need to be reminded of the situation they are in. Yes, the capitalist system is oppressive. Yes, there are systemic issues that prevent us all from succeeding. That doesn't mean there is no situation where decision making is a factor. Sometimes, you do actually need help making better choices. This isn't to shame people for making bad decisions, sometimes there are psychiatric reasons, sometimes they genuinely don't know any better, but you still should speak up so they can potentially correct the problem and learn.
This rule effectively creates a hug-box where we all pretend that personal responsibility doesn't exist, that there is simply nothing to be done. It's incredibly infantile, it's a cope, and the people in this community deserve better than that.
EDIT: I feel I may have had a change of heart after reading the comments left by @EelBolshevikism If you are looking for a somewhat comprehensive response, those comments are likely a good starting point.
I totally get that, and that's why a big rule here is that this is the only place on the entire site where people are allowed to make these kinds of requests for money or help. Since lemmy allows you to block individual communities, no one need any engagement here they don't want. If you block the community, you'll still see the regular posts from users that frequent it, but you'll never even know they do it because the rules preclude bringing it up elsewhere.
This requirement is the main reason a block button for communities was implemented into lemmy in the first place, and as a result we see this community thriving only after that boundary become solidified. It's a step closer to getting a coherent system of informed content warnings going.
