Hasn't all money been taxed before?  When I receive my paycheck, it's taxed, but hasn't that money already been taxed when my employer took in the money?  And wasn't that money taxed when the person who spent that money on my employer received that money in the first place?  That argument seems moot since we don't tax money in this country (or any other I know of), we tax people.  My money doesn't fill out a tax form in April, I do.
