you’d quickly learn just how entitled and oblivious so many pedestrians act.

Well yes, they are indeed entitled to what they are doing. It is you who is acting entitled here - cyclists are not entitled to having pedestrians dodge them.

Your earlier vehicle example is wholly misplaced. Divers have a legal responsibility to maintain awareness of their surroundings at all times. Pedestrians do not have that. Notice that many disabilities can legally disqualify you from driving.
