I think smaller government is often more responsive. The Czech Republic is closer in population to some of the US states.
>...So what do libertarians represent really? Quick search for "libertarian manifesto" shows https://mises.org/library/new-liberty-libertarian-manifesto which talks about abolishing nation state and such.
I think Rothbard is probably promoting anarcho-capitalism there. Many libertarians would probably consider themselves closer to classic liberals. For example, here is a quote from a professor at NYU:
"...I consider myself both a libertarian and a classical liberal. … So there are important differences among liberals and libertarians but I view these are differences along a spectrum. Some are principled (“Never, ever, initiate the use of force”) and some are empirical (“Many public goods can be provided privately”) and some are hard to classify (“The NSA should not collect masses of meta data”). Some people will want to take these differences and harden them into different political philosophies with different names and so forth. But I suggest that libertarians and classical liberals have too much in common for any divorce."

More practical ideas can be found in the works of groups like the Reason Foundation. As I mentioned in a different reply, at reason.org and you can probably find hundreds of pages of commentary, practical solutions, reviews, etc. The top story on the site looks like it is on the details of the current state of the air traffic control system. You can read the digital version of their magazine for free and in fact every issue they have ever published for close to 40 years. Another group is the The Institute for Justice (ij.org). IJ is a libertarian non-profit law firm that in their words:
>...Since 1991, IJ has come to the aid of individuals who want to do the simple things every American has the right to do—including own property, start and grow a business, speak freely about commerce or politics, and provide their children with a good education—but can’t because they find the government in their way.
IJ have brought 5 cases to the US Supreme Court, winning four. The case they lost was the Kelo case but there was a big enough outrage on that decision, that a number of states put in protections to their eminent domain laws.
