We should repeal every minimum wage law, yes. They were created a century ago with racist intentions, their effects are still racist and yet today they are defended as being "anti-racist." The actual minimum wage is and always has been $0, and more people get to (not) work for this wage in the minimum wage regime than would without it.
I have yet to see a reason why a body of torts and collective bargaining would not be completely effective at resolving the real issues that need solutions in labor law and workplace safety. (I'm not sure what you mean by "anti-compete" laws in a labor relations context.) The existing regime where administrative bureaucracies are essentially intermediaries with perverse incentives to reduce exchange between two otherwise consenting parties seems like the worst possible world.
To reframe your question, I think the solution is not "no laws," but laws that encourage more exchange but in a way that reduces power imbalances between consenting parties and give the parties a solid basis of legal (or equitable) recourse for undeniable wrongs that happen that were not anticipated by the contract.
