Are you Libertarian or do you have a non-partisan objection to the IRS specifically?

In my experience, "starving the beast" just means you're locked in a room with a starving beast. Bureaucracies can be awful to deal with. But if you strip them of resources, the laws that dictate their mission are unchanged. Any hope of expedient resolution of issues is gone. People who, often through no choice of their own, must deal with these bureaucracies will receive worst treatment and outcomes. Unpopular though the IRS may be, an IRS that can't function correctly is more dangerous to individuals and society than one that can.

I'm struggling to think of any legitimate objection to the IRS that could be non-partisan.
