What other purpose could player housing have? It is 100% useless for everything other than trying to show off to people who care enough to look at your house. There is LITERALLY no other reason to have it. Doesn't help in any way, shape or form. Adds absolutely nothing to the gameplay. Doesn't add any new content other than looking at what people make their houses look like. It's completely pointless, and I've yet to see anyone give a reason it should exist other than "I think it would be fun" and when asked why it would be fun they say "Cause you'd have your own house!" well yeah, fantastic... Except not really.
If you're that interested in making a house you can always go play the Sims. And that isn't $15 a month.
