Good points.

Side note: I am a US citizen, but I live in the Czech Republic at the moment, so I would be interested to see a system which would be flexible enough to allow any government to utilize.

This actually seems like an interesting enough problem that I may try to code up a website where people can anonymously enter how much tax they pay (in currency amounts) and how they would allocate it (in %). Then try to do some aggregates to see how countries would compare.
