Not if you want tariffs on top of income taxes, you’re not. Libertarian is a neat sounding epithet but to be credible you have to talk like a libertarian.
One could suppose that Free Traders wanted the penalty against income tax instead of imports to push more people into becoming destitute or dependent upon others. You certainly prefer the income tax to excise taxes, it appears. I don't.
Since the excise tax was greatly reduced to ostensibly help free trade proponents as the income tax came into being, we are now in a world with both taxes. Since we have both legally available, we should minimize the income tax and have parity with it in the excise tax, which should be levied across the board at the same rate as that of either the income and business tax. If we could reduce the income tax to 5%, the excise tax could be the same. If we had a National Sales Tax, we could get rid of the excise and income/business taxes, to the extent that our regulations did not put an added burden our our home industries and businesses over that of lesser regulated business products from other countries.
Eliminating what the federal government “provides” minimizes the tax burden.
Ideally, I would like the US to be more like Singapore or the former Hong Kong, but with an adequate defense. We should go all out being the capitalists we are bred to be and not the socialists we have become (ironically, since the income tax was passed to reduce the excise tax).
