Your points pre-suppose parties consented to a dispute resolution system: one that is based on arbitrary boundaries and quite monopolistic (1).

So, I agree that it is hard for people to understand what consent is when they were never given a chance to choose which dispute resolution system(s) they can participate in.
(1) Example being I was born in the USA so somehow automatically consented to the rules of the land.
