Nice try, but the ideal market does not exist in the real world. Some markets are more "ideal" then others but none are perfect. As a result, government has to impose regulations to ensure the market is as close to ideal as possible. At this point capitalism can do its thing and optimize for efficiency. Without said regulations the market does not balance, corruption and/or monopolies emerge, and consumers are generally screwed.
Regulations should be minimized but never removed entirely. I personally support a system that regularly reviews regulations to ensure they still serve their original purpose. At times, updates will be required. So be it - regulations have to evolve with changing markets in order to ensure the market remains healthy. But any person (or organization) who claims that regulations have to be abolished is either horribly naive or has vested interests. All those lobbyists come to mind. Lobbyists are important because they inform government on the cost of regulations - but giving them all that they desire is never in the public's best interest.
