The involvement of government in particular does not concern me.
My concern is the involvement of any powerful group.
If all you seek is a reduction of the state, you leave a void waiting to be filled by corporatocracy.
The argument of left vs. right, authoritarian vs. libertarianism is a red herring, what really matters is the distribution of power. Given that money is approximately power and that the government is more accountable to me than an individual, I have no qualms about the higher tax rate.
