Economics school dorks: theft is a signal that the price is too high, but only too high relative to the potential cost. The fact that stealing is illegal is what makes it a valuable price signal in the first place. Here look at this series of charts that show my point-

Why should that philosophy not be extended to all things?

someone stole your personal property? that's bad

someone stole your private property you were using to extract rents and surplus value? oh no, you might have to sell your labor

Same with squatting.

The best leftist take on stealing is that it is wrong, but (especially under capitalism) there are many excusable instances of it (that is, stealing from the right person for the right reason).

Every society I'm aware of, including all AES states, has some laws about property and some prohibition on stealing. Same for every religion. "Legalize theft" is a silly and futile battle to pick. Encouraging people to reassess when stealing is OK -- that is, situations where the degree of need outweighs property interests -- makes much more sense.
