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.
