See #102.. Try to critique my actual words & concepts, as written, -- if you can.
If you can't, please find someone else to pester.
"We the People" have the valid Constitutional power to legislate on such matters.
If such matters are to regulate commerce, license enterprises engaged in trade between states, or to prescribe the form, size, quality, measure, labeling, scheduling of such trade; and to impose civil penalties for violation of such regulations, such as fines or loss of licenses, then my answer is dependent on what is meant by "valid."
If "valid" implies a Constitutional power to do such by "We the People," then I agree. If "valid" implies a moral right, I disagree. The libertarian position has been for at least the past 50 years, that no government should have such a moral right.
If you advocate that government does have such a moral right, then I'm right, you are not a libertarian.
Correction to my last reply to you. The above sentence should read:
The libertarian position has been for at least the past 50 years, that no government has such a moral right.
or
The libertarian position has been for at least the past 50 years, that no government should have such a right.
