I know they sound rhetorical that's why I clarified haha.

With the lowered top speed, acceleration, cornering speed, the stops a bus makes for other people and a bus never goes exactly where you need so there will be some walking involved all increases the travel time.

I am also not talking about the cost to transport 5 people. I am talking about the viability to transport 5 people's worth of groceries over that distance. For example a mother of 2 can't have her 3 children under 10 carry groceries for an hour every second day, and you can't do it on your own.

Perhaps you are right about this sub being the graffiti on the walls but is undoubtedly the face of the movement, making it the most important place to have your objectives be clear
