The guy in Seattle is a capitalist. If you don't like his decisions, you are free to ignore him and not do any business with him. Of course, many of his decisions do benefit you -- low prices, free delivery, wide range of products, displaying reviews, etc. -- but again, you aren't obligated to participate or interact. In fact, even if you refuse to buy from Amazon, you still benefit -- because of competition, your favorite store probably also offers free delivery or has low prices because it needs to compete.

If a committee of Senators, on the other hand, makes a declaration -- Amazon cannot sell Chinese goods cheaper than American-made alternatives -- or maybe, delivery times to rural areas must match those to cities -- then everybody loses, and you can't opt out of that.
