Because I believe it is simpler, more efficient, and more fair if a centralised body deals with the distribution of funds.  If there was some organisation that did this instead of the government, I would be equally happy to use it, but the benefit if including it in taxes is that everyone pays and there's no forgetting or 'getting round to it sometime' involved (never underestimate the power of apathy).

I have to say that the US IRS is pretty damn efficient at collecting and disbursing money.
