Government didn't "take" power during Prohibition is was done through the only legitimate means of increasing Government powers-- the resolution of a Constitutional Amendment; nevertheless the power to reinstate or even expand this power could be achieved today without such an amendment. There is nothing whatsoever preventing re-institution of the draft, except that senior DOD leadership knows that drafted soldiers aren't nearly as effective as an all-volunteer Army and scream and howl any time the subject is proposed...
Of course it did. There are only 2 options, taking power or turning it down.
Well, government did not turn down the power of Prohibition. It took it.
