I am against paying unrealistic taxes.
I am personally opposed to all kinds of theft, but if you are the sort who doesn't mind it as long as it comes from your government, paying capital gains on an asset that goes from $60 to $500 in a few months isn't unrealistic. If there is stability or the asset loses value, you don't owe anything.
I don't believe its quite so simple as blatant theft. At least some of the tax money maintains roads and schools. That's why I don't mind paying "SOME" taxes, but I certainly agree that we pay WAY too much tax, and the government has gotten WAY too large and they are WAY too inefficient.
