Liberty = democracy.
They are not motivated by self-interest, they merely factor it in when deciding how best to ensure an efficient just democracy. The libertarian model based on legitimate empirical science, factorring in the human capacity for both selfishness and altruism.
Ayn Rand was an anarcho-capitalist, just another type of marxist, nothing to do with science and thus nothing to do with libertarianism.
Game theory is just some abstract mathematics and claiming that it represents all of libertarian political science is absurd. Libertarians lean towards more empirical treatises for insights into human social systems such as Niccolò Machiavelli, Thomas Hobbes and John Stuart Mill whom include more variables. Of note is the fact that many non-market based government institutions use game theory heavily.
There are more mature profitable sensible applications for investment instead of just "AHAHAHAHAHAHAA IMMA PUT MAI FALG ON TEH MOOON FERST". Investment in theoretical physics, environmental studies and astronomy would come from the private sector if the state did not monopolise it. Billions are spent on research and development and investment in new technology every year, by far the most by US corporations because the government interferes less there.
You are not being held captive by a nanny state and it requires cooperation in the democratic forum of your nation in order to replace the nanny state with superior market alternatives. Libertarians explicitly believe that the state's only purpose is to equalise power, this means a libertarian state would exist to pay for an army, courts and police. As for the supposed dependance on state funded infrastructure and public education, we are inly dependant on them because by law the government can steal money from us and make us pay for them. There is nothing we can do about it except evade tax and vote libertarian and I do both so don't look at me and claim I am dependant on them.
