What worthwhile thing can “only” government (by which I mean, The State) provide?
I can imagine many voluntary ways to provide anything needed and wanted. But, a free society wouldn’t be limited by what I can imagine, so someone would undoubtedly come up with better solutions than I can possibly imagine.
Liberty is the Mother of Innovation.
In fact, we manage to find many of these solutions in spite of government trying to stand in the way every step of the way. Just imagine where we would be without that huge, costly roadblock.
So, keeping government around, because you believe it is necessary, is very silly.
