Of COURSE we will never be completely libertarian, just like we will never be completely capitalist or completely socialist. That the libertarian Ron Paul camped out in the GOP is the best thing for the Republicans since Reagan came along. I am pumped by the energy provided by Paul followers and I want to see the GOP move in that direction.
You said "It's not a true libertarian Paraty" well doh. No kidding. There IS an official libertarian party around you know. And they will continue to be marginal.
