Libertarians doesn't suppose that everyone will make good decisions with their money. There may be corporations that exist due to there being a large supply of idiots willing to buy their goods. If that were the case that would be fine. No problem there. There are not right or wrong products, just products of different value. Everyone is free to choose how to spend their money.
What you say about surplus is wrong. If a company is jacking up the prices and making a huge surplus then another company can come in and offer the same products at lower prices and steal the marketshare.
But I think your main problem is you are being pessimistic. You say capitalism fails because people will make mistakes about how their spend their money. But if that were the only problem facing society then surely the solution would be for people to begin placing more value on education. Libertarianism fails because people are too stupid, that's what you're saying. But libertarianism actually helps people see how they fail by being uneducated, thus it encourages them to become educated.
Giving people freedom to make their own choices is not dangerous, it allows people to learn from their choices and become better people. Restricting choice, like, for example, through censorship, doesn't make people stronger, it makes them weaker, it makes them less able to make their own decisions. By allowing people to make decisions for themselves from day 1, they will inevitably become master decision makers. Society will be a better place for everyone.
