This isn't a theoretical, it already exists and it already works. Cargo bikes can deliver parcels faster than vans in some cases, they can carry large loads, ebikes make up for the labour, riders have much better awareness of the world around them than van drivers, and don't have all the extra mass of a van that will cause damage in the event of a crash. And it doesn't have to work in every situation, it can take vans off the road sometimes and that's still good.
Public transport is also limited as the city is highly walkable, which forces me to wonder how much the public transport v cars is a bit of a false dichotomy.
It is also just a pretty small place, there's less need for public transport when everything is within walking distance.
It really absurd how much governmental bending over backwards we make for people to store and move their private property wherever they please (and subsidies)
But only if that property is a car. God forbid you want to use that same space to store anything else.
One other thing I've not seen mentioned yet is capacity. Switching a maglev track is difficult and very slow, which reduces the number of trains you can get through a switch and therefore the number of people your system can carry.
That station was just built ahead of other development (which is a sensible thing to do), this is what it looks like now:
