I fully agree, the biggest risk is, was, and will be, the option to change the code. Some how we must go back to a more pure baseline, and make each and every change way harder to impossible. Additional functionality should be made like Lightning: on different layers than the Bitcoin base layer.

You are inverting things. Bitcoin was designed to florish outside the whole centralized world including 'property rights'. If you, or something can sign with the private key the transaction is a 'fact'. Get your mindset outside the made prison. Bitcoin can help you with that but can't do it for you !
