With that I totally agree, humans make mistakes.
They also act maliciously sometimes. There are powers that understand how deadly is BTC for their privileges. They are sure to try their best to take it down by making it look buggy, sloppy, unsecure, etc.

I never said BTC can't be touched. Bugs have to be fixed, including fast track fixes be there the need.
What I'm strongly opposed to is adding fancy unnecessary stuff. The more complex a mechanism is the more points of failure it has.
