Slightly tongue-in-cheek: One could be cynical, but not necessarily incorrect, and state that Part 103 and all the other flavors of GA are a giant, money-sucking PITA to politicians, authorities, and air-gods with a lot of liquidity and a lot of friends. The promise of smaller-government in the future brings with it the potential for simplified, easy-to-enforce rules. Simplified and enforceable rules are often heavy-handed and arbitrary, and favor those wealthy enough to write them. Good luck to anyone selfish enough to aviate soley for self-actualization, and not for the benefit of corporations and billionaires.
