I think there should be restrictions on where to park for this, but in general people found sleeping in cars should be protected by the law against theft and harassment.
Most hallucinogens (at least for medical or supervised use)
Being trans (lotta states trying to ban me)
Being gay (they're probably next)
Abortion (many states ban this now)
Free healthcare (not technically illegal, per se)
Being homeless
Polyamory (not technically illegal afaik, but there are a lot of legal benefits that married couples get which aren't extended to polyamorous relationships due marriage being restricted to couples only)
The list goes on because while there are many basic things that aren't technically illegal, the system is set up in a way to fuck you because of the required profit motive behind offering basic necessities in a capitalist society.
Abortion. No specific circumstances needed. If a woman wants an abortion, it should be allowed. There is no one getting late term abortions that didn't want the child and something tragic happened and now they need one.
The cruelty to force people to stay alive while slowly dying and suffering with terminal diseases is horrible. It’s traumatic for everyone involved, and it’s pointless.
For now all I can think of are drugs (every single one, including opioids) and euthanasia (not just for terminal diseases, should be available for everyone who decides to).
