Travel
I don't understand people who want money to travel yet can't stand the diversity at home. It also seems that the only people who get to travel are those that are sick of it - business travellers on commutes to the four corners of their corporate empires. What we really need to do is get the trailer park population to do all that travel for them. The business guys get a break, and the trailer trash will learn new and exciting things, like that Africans aren't cannibals, or that in Russia guys kiss without being hit by meteors.
Or how about those pointless vacations to exotic countries, where people never set foot outside the walls of the resort? Save some cash people: turn your heater to full, leave a hot shower running for humidity, throw some sand on the floor and lie there. Buy postcards at mall-wart and use itching power to simulate sunburn.
And don't you hate trying to cram everything into a suitcase when you're travelling? All of that stuff is available where ever you're going - so why is so much work, space and fuel wasted on it? Would a transport company repeatedly fly all that stuff all over the world?
Without property, things could be left behind and be freely possessed. Once you're at your destination, you could possess anything available.
