No one is stopped from creating a third party. There are a ton of them out there. Libertarian, Green, Constitution, Natural Law, numerous Socialist Communist Worker style parties. The problem is getting access. One of the few things the two major parties have been able to work together on is creating rules to prevent these parties from participating in debates and making it difficult for them to even appear on the ballot in most states.
