The bike in that image appears to be a manual bike, like your peddling supplies all the input for movement. The cargo bikes you are mentioning are all e-bikes, they are all custom designed for a relatively small number of orders, are overengineered/overbuilt to handle the extra weight of an e-bike, have hydraulic brakes because it is so heavy, and have a battery and motor. That's what the Urban Arrows are, for example.
You can get a used cargo bike (not electric) for around $500-750 in the US.
Thia is still somewhat expensive but part of that is the overall bicycle industry being based on new expensive components.
The only examples I've seen of this are people saying it's antisocial and counterproductive behavior to crab dance this pope's death. It definitely is antisocial, it's only something a small group would enjoy and most would be very alienated by it.
This is just a fact of what it is. For some it makes sense to embrace the antisocial, often creating and preferring a new in-group. Unfortunately this tends to mean cloistering oneself and failing to actually build anything, and adopting habits that prevent it.
This forum's name was originally from a podcast by not-particularly-funny white guys in New York. They have not actually built anything. They are not of an organization. They don't mobilize anyone to do anything. They make snarky jokes poking fun at the liberal political establishment and electoral politics and are increasingly irrelevant. That is the inevitable trajectory of seeking conflict and infighting and being eagerly disrespectful to your comrades.
