Beyond that, part of the Libertarian line of thought is that we have to "let go" and let things fall where they may because we have no moral claim over it. The area of effect we have as individuals is quite small so it makes sense to focus in that direction rather. So that would mean things like family, neighborhood, community, shared culture/religion, and the institutions that build on those.
I myself try to be involved with and sit on the boards of HoAs, to add some sanity and fairness to it. I've also been helping pay for close family friends to go through college. I'm also planning on doing charity work for the groups I feel closest to in my local context (South Africa).
It's like when you reset your tastebuds and the level of sugar and salt in everything becomes physically revolting.
I don't expect a mass enlightenment any time soon though (regardless of legalization/normalization of psychedelics), so we'll need one or two (or three...) "stopgap" solutions before that point. (Just for the next thousand years or so ;)
A somewhat related phenomenon is the desire for someone else to take care of everything. It simplifies the infinite chaos and complexity of life. To some degree this is necessary to maintain sanity, but if this is the "default" approach, except for a small percentage of people who seek power due to genetic hardwiring... well then you end up with what we have now. In this case, the solution is also maturation (though in this case, emotional rather than... whatever you want to call consciousness being aware of itself), and also not expected to "arrive" within the next few centuries.
I wish I had some more practical suggestions, but I at least hope that pointing out the root causes (as I see them) may lead someone else to helpful ideas.
Hate speech on social media? We can't ban that, it would be a slippery slope to fascism. What even is "hate" anyway?
Algorithmic feeds? Fascist mind control. We must only allow strictly chronological feeds or it's the reeducation camps for us all.
The kids these days and their memes? WHAT DOES RIZZ EVEN MEAN? BURN IT ALL TO THE GROUND AND SALT THE ASHES.
On the other hand, if anyone wants to try making advertisement contracts unenforceable (illegal, essentially), I'll be the first in line.
