Your post doesn't make sense. If that provision actually establishes
rights to free activity, including economic activity then economic activity cannot be regulated and so there can be no question of whether an activity is permitted by law because such laws would be unconstitutional.
But your conception of the Amendments is obviously wrong because economic activity has always been regulated by state and local governments.
I did not propose that no economic activity can be regulated. I was asked what specific provision in the Constitution authorizes sellers to decide what they want to sell, and I answered that this is ordinarily an unenumerated right under the 9th and 10th Amendments.
The state can enact reasonable regulations, but in this case I say they ought not require the provision of harmful and lethal drugs. This is not a matter of individual whimsy. It has been an explicit part of medical ethics for 2500 years.
