It's not semantics. Capitalism doesn't mean an 'unregulated hellscape', capitalism requires a state to exist in order to defend the right to hold private property. In capitalist countries, the legal system functions mainly as a way to defend the rights of corporations, with occasional compromises to prevent an uprising (e.g., $1200 checks during the covid pandemic).
If police didn't exist, corporations would have to hire private security to defend their property - and in fact, this is what they did during the 1800's.
For an example of what an "unregulated hellscape" looks like, take a look at the world of cryptocurrency and how common it is for people to get all of their property stolen.
