The kicker to that is not everyone has liabilities, everyone's circumstances are different though which is great.
If you can run it through a business or some other entity then leasing to me makes sense to me. But again, everyone's circumstances and structure is different. If your paying out of your own pocket, I agree with Sam your better off putting money in appreciating assets than borrowing against depreciating ones, but that's just me. The beauty of it is everyone does what suits them.
Real estate and the share market doesn't double every 5.5 years either.
