Blizzard keeps adding solo and multiplayer content and ignoring social content, so there's every fear that they will screw up housing in this way as well. I mean that's basically the problem with garrisons. It was either solo stuff or just some very bland and boring multiplayer action with no actual social component. People hate that.
Blizz needs to understand there is a difference between people just interacting without talking and then never seeing that person again, and actually building a social world.
