Economics, pressure, etc. is not a problem. Only the timing hasn't been right so far.

I think pointing out what it theoretically possible given unlimited funds and no need to make a profit is easy. I would like to see someone actually propose a scenario in which it make economic sense to build an enormous underwater metropolis as depicted here. Any actually underwater communities will most likely have a completely different form to match the challenges of sea.
As far as Virgin Galactic's space tourism goes, that company has made a calculation that they can eventually make a profit by charging customers $200K per person for suborbital flights (or that even if they do not profit, later developments will lead to a profit).
If you can build an underwater city that can contain 500-1000 foot towers and house a million people or so and show that they will be able to afford to live there, then my hat is off to you!
