You stopped short. You quoted the first paragraph but not the the supporting clauses. In fact, that preamble then goes into enumerating the specific federal powers. If it was enough to say that taxes, duties, and excises could be levied and collected to pay for "common defense and general welfare", Section 8 would conclude with that sentence.

Allowing the federal gov to tax for "general welfare" gives it unlimited power, which contradicts the very structure of the government.
