Means trade goods should move freely among the states with no tariffs or duties or other obstructions attached. Has nothing whatsoever to do with health care or health care insurance (or the manufacturing, production processes, etc, btw).
Correct. And should insurances move freely between the states without obstructions? Insurances are services that are purchased, are they not?
Has everything to do with making commerce regular.
If we follow the narrow view, then no service or good is to move freely amoungst the states, indian tribes, or foriegn nations.
Is healthcare a interstate commerce service? Or is it now a state only commerce.
