No, not at all. There's just no need whatsoever for trucks.
We could simply use rail.
The idea that folks on bicycles should be subject to gigantic, badly designed commercial vehicles while going about their business is absurd and a product of decades upon decades of lobbying.
You don't have (and IMHO can't have) rail directly to all the businesses and retail warehouses that currently receive deliveries in semis, so that's adding a significant expensive extra loading/unloading step for large trucks which you still need between a rail station and a distribution center before the 'last mile'.
The one thing trucks have that rail doesn't: flexibility. You need to lay a lot of track - and have lots of small trains, often only pulling a single container, to get to even approach the same flexibility trucks have, in speed, in location, and in routing.
Sure, Just In Time is partly to blame for this. But if your stock intake deliveries now become a monthly event, you need to build a warehouse that holds about six weeks worth of raw material. That's cost.
And unless these folks on bicycles delved for and forged the metal for the bikes themselves, assembled the self-made parts and walked all the way to the Caribbean to get the tree juice for rubber tyres, chances are, a truck brought the bikes to them.
The trucks that endanger cyclists aren’t going anywhere. They’re absolutely necessary to get goods from rail depots to markets so (among others) our dear cyclists can purchase them.
It's possible to restrict vehicle size in urban centres, plenty of cities do. You can move things with smaller safer trucks and vans for the last mile. In some cases, this is even done with cargo bikes.
I guess my point was “the trucks doing the last mile delivery aren’t going anywhere”, contrary to the parent’s claim that trucks are unnecessary and that rail will handle the last mile. I fully expect trucks will get smaller if only because no one is going to use an 18-wheeler to transport goods between a rail depot and a supermarket a mile or so down the street.
I don’t think rail will handle the last mile in all cases, but I also don’t think the last mile requires trucks. It’s the last mile. There are so many options besides semi trucks.
It’s worth looking at Switzerland where they have many electric spur lines that do handle the last mile.
You can repackage stuff and move that to urban centers ... but that comes with cost again. Cost that will be high enough so that urban centers don't make sense to deliver to anymore.
