True, but unfortunately, this species is way over-planted in many cities. I would not recommend them unless they happen to be uncommon in your local area. Urban forests need to be as diverse as possible to resist the constant barrage of pests and diseases being introduced by global trade.

In California we have a relatively new pest called shot-hole borers which are killing off many of the London planes, so we’re scrambling to plant other species that can resist them.

Also, resistance to air pollution isn’t as crucial as it once was due to better emissions technologies.

Your potted tree isn’t a tree in the sense that I’m talking about. The environmental services trees provide are all based on size and so are predominantly provided by larger trees. Cities usually avoid planting these under electrical wires and in smaller tree basins to avoid damage to infrastructure. So practically, there are many urban locations where big trees won’t fit.

Trees don’t attract VC funding the way some dumb new invention does.

I guess this could be useful in places trees don’t fit but I think there are other simpler solutions.

The amount of water required is trivial compared to most other water uses. Especially if correct species are selected.

I wish, I see them pretty regularly.
