IMO, we need to stop having people control one another. There is no self-interested reason to do it, from anyone's point of view.
That said, many, many, people believe that most people are not competent, and need to be taken care of/controlled/limited.
Arguments I usually have to fight against are: What to do about crime. What to do about "evil" people. What to do about property rights. What to do about control in decisions.
There is a simple solution to all the problems you mention, which is to have a government that uses retaliatory force, but not initiatory force.
America had one for about a century, and now there is the intellectual machinery needed to go back to that system and to define and defend it much more vigorously. Unfortunately, a majority of "advocates for freedom" are mucking around with things like "libertarian socialism" and "anarcho-capitalism" which are contradictions in terms and won't work.
Unfortunately for you (until or unless you stop fighting the truth), objective knowledge is possible.
