Nobody needs a house and frankly I think it's silly that they're required for access to any feature period. There should be other ways to crossbreed and other ways to access an FC workshop given that the system as it stands is so limited.
And yeah, a two week timer is pretty unreasonable as already said, business trips and vacations can easily end up in the realm of two weeks, and chaining people to the game even more than they already do to keep a house is just crappy. I'd prefer if there was enough housing to not have a timer at all, ESPECIALLY when they don't even save your furniture when your house is demolished. If you can't get on in time to save what you can, it all goes poof, including stuff that cost actual real life cash (which I also think is ridiculous in itself).
I doubt they'd fully overhaul the whole system, but if they do, instanced housing would need to have all the same features as current housing to even be all that appealing. Size, furnishing, gardening and exterior decorating, and sharing the house with friends are a big part of what I like about housing. I'd happily move to one if it meant I didn't need to worry about a demo timer, but only if it was actually, you know, a house. As opposed to the apartments we have now that are frankly vastly inferior.
