Isn't it ironic that

You should only be taxed when you spend your money.

A) Would that not mean a black market economy? andB)this tax exists already in VAT or whatever it is called in the different countries, of course together with the income tax so not so high that everybody buys 90% of their things on a black market C) this means also that a government will try to let you spend as much as possible?
Would this also count for second hand things? And if so would that mean that the government could make a few times the value of a car made by somebody? And if not would that not make the difference in price between new and second hand things so big that people buy a lot less new things (which is negative for consumerism) How would this work between different countries? If I come from a country with income tax, i would never in my life buy something from a country with pure sales tax.

I like the idea....I am however not sure how to make this work.
