I know people (including myself who actually owns a house) who would love to (or already do) travel the world. Buying and selling houses in every location you travel would be a hindrance not a help.

There is no black and white, this is an ethics discussion, there are shades of gray for everything. Just because you want to stay in one location and never move doesn’t mean others want what you want.

Edit: adjusted sentence to make it easier to understand
