Fundamental flaw of libertarianism is in not understanding that to implement their goals it will require a iron fist approach. Yes, you will have to force people to be free before you can walk away and let nature run its course.
Shutting down social security is not something that would happen quietly nor easily.
More freedom most certainly can be the end result, but the temporary means to get there isn't going to feel good.
You just expressed in your statement exactly why I said what I said. The majority will not vote for freedom, they do not want it and will actively fight against it. The only way to implement it is to forcibly rip away the chains.
People will always vote for safety over liberty.
I think Tombs is right. (Seriously.)
Freedom is scary. Liberty is dangerous. (And I'm not just talking Liberty Sanders.) With more freedom comes less safety net, more chance of ending up in really bad shape.
Rather than that being a motivating factor, pushing people not to mess up, generational decision to provide a gov't safety net have caused ordinary Americans to expect that safety net. Then, to expect more of it.
I don't think an "iron fist" is the right analogy. It is more like kicking a fledgling bird out of the nest so it can fly. Yes, it is a cold decision, but necessary for that bird to grow.
It doesn't take an iron fist to force people not to take social security. That doesn't make sense. You just take social security away. I'm not saying that's a good starting point - it isn't. Its a terrible starting point. But, we can probably start with some of the cheaper, more narrowly focused assistance programs to scale back. Incrementalism.
(Plus, GenX and younger aren't even counting on social security anyway.)
