What you think...

The "legit" reason is that Yoshi.P and his team seem to believe that wards are a superior system compared to instanced housing (which traditionally makes it much easier to balance supply and demand) but are unable to deal with issues such as supply and demand disparities or server capacity limitations.

So while there was no "arbitrary" decision to limit the supply itself, that supply is limited a result of an "arbitrary" design decision to pursue 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.

I'm pretty sure I read that making housing hard to get was by design. Because they wanted players to feel rewarded when they got one. There's also nothing wrong with this design and it's bound to generate some disappointment (like everything difficult to obtain).
The real problem is that SE did not properly evaluate the difficulty level, and walled it behind the randomness of logging in right after a patch.
But yeah if you're complaining about it being hard you're essentially comforting their design (not you personally). If you notice this housing expansion wasn't about personal houses but FC housing.
