Apportionment only applies to some taxes, the ones that are direct. Indirect taxes are not subject to apportionment. Examples of indirect taxes include excise taxes on liquor, income taxes on wages, tariff on imports, Capital gains tax, fee of 200 dollars on manufacture of a firearm, and, post 16th Amendment, income tax on income from property.
That the indirect taxes are legal per the apportionment clause doesn’t make them right. It just means you need a different argument.
Aside from that I get the feeling you have a problem with the very intentions for which the rule of apportioning any general tax among the States was adopted. Am I correct in thinking this?

“The proportion of taxes are fixed by the number of inhabitants, and not regulated by the extent of the territory, or fertility of soil”3 Elliot’s, 243,“Each state will know, from its population, its proportion of any general tax”3 Elliot’s, 244 ___ Mr. George Nicholas, during the ratification debates of our Constitution.
