So while there was no "arbitrary" decision to limit the supply itself, that supply is limited a result of an "arbitrary" design decision to purse a particular housing system model. And while I can certainly see where the devs are coming from and even agree that in many aspects wards are superior to instanced housing, I don't think it justifies maintaining a system that just doesn't work well enough for years while also refusing to consider alternative solutions.
It is possible to make a ward system with much higher number of wards. See for example LOTRO which has a similar housing system with various neighbourhoods ( = wards) each with a number of houses in them. Difference is that they have a much larger number of wards. Not infinite, but near enough in practice. Main difference is likely that there each ward is treated as an instance, which might lower server load.
