I am not arguing that we metaphorically and literally need to do away with locks right now, but that we can and should apply effort in the direction that makes them obsolete as preventative measures. I want to live in a place where I do not need them.
The existence of trustless systems does not make distrust mandatory, it is such systems becoming mandatory that bothers me, as well as the effort spent into developing more and more robust trustless systems—as opposed to trying to make those very systems obsolete by eliminating the underlying motivations that push people to exploit trust.
