It is a great start.
My reservation is that DeSantis's proposal doesn't seem to include the following imo.
DeSantis's proposal needs to include safeguards that help to prevent corrupt political parties from working in cahoots with "follow the money" industry to abuse government power by forcing people, by means of their taxes, to buy junk science remedies for government-manufactured crises.
Also, I suspect that DeSantis may not be up to speed with the constitutional reality that the states have never expressly constitutionally given the feds the specific power to dictate peacetime INTRAstate healthcare policy, not even to try to stop spread of disease imo.
”State inspection laws, health laws, and laws for regulating the internal commerce of a State, and those which respect turnpike roads, ferries, &c. are not within the power granted to Congress [emphases added].” —Gibbons v. Ogden, 1824.
"They form a portion of that immense mass of legislation, which embrace every thing in the territory of a state not surrendered to the general government. Inspection laws, quarantine laws, and health laws, as well as laws for regulating the internal commerce of a state, and others, which respect roads, fences, &c. are component parts of state legislation, resulting from the residuary powers of state sovereignty. No direct power over these is given to congress, and consequently they remain subject to state legislation [emphases added], though they may be controlled by congress, when they interfere with their acknowledged powers." —Justice Joseph Story, Article I, Section 10, Clause 2, 1833.
"From the accepted doctrine that the United States is a government of delegated powers, it follows that those not expressly granted, or reasonably to be implied from such as are conferred, are reserved to the states, or to the people. To forestall any suggestion to the contrary, the Tenth Amendment was adopted. The same proposition, otherwise stated, is that powers not granted are prohibited [emphasis added]." —United States v. Butler, 1936.
