BULLSHIT!

Libertarians are for example in favour of Private Education, something which gives better tools to those born from wealthier parents who can afford the better schools than to those born from poor parent's who can: providing people who were lucky to pop-out of a wealthier vagina more/better tools hence more/better chances in life than others is literally the opposite of Meritocracy.

Ditto for Inheritance legislation: it makes even the most inept, lazy-ass, destructive scion of a wealthy family out there have far more chances and power than even the smartest, most hardworking, most able creator out there from poor families.

And lets not forget keeping Land Ownership as is now locking in centuries (in some countries millenia) of the most anti-meritocratic methods of acquring it and a gigantic advantage which is passed down the generations through inheritance, all this, again, the very opposite of a "fair playing field where everybody has a chance".

Libertarianism just wants to remove the Power of the State, a system which is managed by people elected by citizens in a "all votes count the same" process, by the Power of Money, which is mainly the product of past injustices, dynastic and were power has an extremelly uneven distribution (with some having hundreds of billions of times more power than others).

By wanting to weaken the fair playing field (one person one vote) in access to power which is vote by severely reducing that which that power controls (i.e. reducing the State) and replace it by an extremelly unever form of power, Money, which is so unfair that, like in the times of the Monarchy, it is Power which is mainly inherited, Liberarians are some of the most anti-Democratic anti-Freedom people out there, not to mention extraordinary hypocrites.
