The Government Shouldn't Decide "Winners" in Business

The government should decide which business is going to be "the winner" in any capitalistic system. So, from my standpoint:

1. The Small Business Administration should, at a minimum, stop giving small business loans, because they are choosing which "small businesses" they deem to have a plan for success vs failure.
2. All farm subsidies should be stopped. If a farmer can't survive without the government deciding farm businesses are "winners," then let them sell out to a bigger farmer, form a co-op, or sell the land to a developer who will do something else with the farm land.
3. Politicians should stop, immediately, placing loop holes into the tax structure to favor a single business or a class of business. If that's not picking winners, what is?
4. Privatize the patent and copyright protection system. Since the government is involved, it's picking winners and losers in both areas.

The few items above are what comes to mind right now. Is this a liberal idea? Is it a conservative idea? Is it a libertarian idea? Or is it Constitutionally based?
