1. Flat rate income tax. Unfortunately, we'd the have to deal with millions of unemployed IRS workers. Not even so sure ANY income tax is constitutional:

2. Get off the cases of people trying to exercise their civil liberties. Gays in the military, fine. Prostitution as a profession, fine. Drug use, fine (think how much money and jail space that would save! Addicts make their choices, despite laws. And I promise you it would be highly welcome to terminal cancer patients, who are screwed at present.)
Many other examples: ethnic groups who see dog or horse as a food, as a random example. Why on earth should the government tell us what we can or cannot eat? Sorry, abortion goes on this list. Personal choice, between patient and doctor; not the government's business. Does not matter what I would do; neither me or a legislator gets to choose -- you do. Big deal to me is that a court would allow this to become a legislated issue. None of their business. Same for guns: constitution says we can have firearms; end of conversation. Just examples.
And yes, I see having chickens as just another example. I actually feel that laws and ordinances against them are unconstitutional. Even roosters. I cannot see any constitutional argument against raising one's own food that would hold up in the Supreme Court. We should certainly have a right to keep food sources, whether eggs or meat, and that is the end of it, IMHO. NYC taxis and barking dogs are much noisier and more annoying, and I don't see anything in the Constitution that prevents us from being noisy, anyway. Even if we give some credence to noise ordinances, which I do not, the fact remains that barking dogs are much more of a noise nuisance than roosters ever thought about being. Of natural sounds. We won't even talk about 4 wheelers or boom boxes.... And I would bet that the background noise of a typical city is louder than roosters, anyway. Where I live is certainly quieter than anywhere I lived in Chicago, despite the neighbors' barking dogs and crowing roosters.
