Have you actually read the constitution? It's very clear in there that they have the right to levy taxes. There's an entire amendment dedicated to the income tax.
Taxes that are to be used to fund the operation of the government, mint currency, national defense, etc. It does not allow for punitive taxation to redistribute wealth, whether it be food, housing, healthcare, cell phones, or any of the thousands of other giveaway programs that have been heaped upon us the past 50 to 80 years or so.
