Seriously, though. It's a rhetorical question that's supposed to get you to think about the concept of value itself. You can't answer the question without defining value. Good luck defining it. It's the question at the core of economics. If you come across the answer let me know.
For me it would depend on the situation. If I was taking a dump in the woods the toilet paper would be more valuable. If I was starving and at Mc Donalds then the roll of dollars would be more valuable
US Dollars are just fine for buying things today. Ok, prices have gone up, but the greenbacks are still spendable. I think the problem will really begin about 3 years from now as more and more baby boomers retire, produce nothing, get checks from the government, pensions, 401k withdrawls, stock and mutual fund sales, and home sales. If everyone is retired and getting checks, where is it the stuff they plan to buy is going to come from?
toilet paper is better. If you have dollars, buy the toilet paper anyway. You can sell it in the UK. That's good arbitrage
Hardly. It's situational. If you are stuck in the woods with nobody else within 1000 miles- $$$ are nothing but paper and the TP would be quite handy. In a area where the populace will exchange goods for $$$s, most if not all would value the $$$ higher.
