Tbh having known a fair number of libertarians and kept tabs on the libertarian party over the years, I am not really convinced that theyd really be an improvement. Their ideas on economics are straight up even more extreme than the republicans and their ideas on social issues boil down to the government just not doing anything to intervene which is less than ideal given that would eliminate policies like the ADA. They oppose the government doing things that harm social freedoms which is good but its at the expense of just letting private companies do effectively the exact same thing based on the theory that you have a choice to be subject to it or not which doesnt really work out in reality if you are effectively chained to your job with no realistic escape and/or the companies you deal with are monopolies (which they oppose antitrust legislation to deal with)

The GOP deserves to be replaced with something else but I am not really convinced libertarian philosophy is the replacement we need. I would rather deal with a party that is more focused on finding market alternatives to government intervention but does not strictly oppose intervention when those market alternatives aren't working or otherwise are untenable. I want a party that at least acknowledges global warming and wealth/income inequality is a problem and that maybe we shouldn't be untethering corporations from all regulation, just the regulations that serve no purpose other than to stifle competition.
