As I stated, temporary, limited orders tailored to achieve a necessary government goal will likely survive constitutional challenge. I was responding to a poster who asked about the constitutionality of isolating the elderly.
Specifically, challenges to travel restrictions have been made arguing that they violate the constitutional right to interstate travel, which is covered by the 14th amendment's protection of liberty. The right to gather together is protected by the first amendment's protection of freedom of speech and assembly. It is not necessary for a government action to completely prohibit the right to gather in order for it to be an unconstitutional restriction.
The US constitution applies to laws made by Congress, but certain provisions have been extended to the states through the 14th amendment. Also, states have their own state constitutions that limit actions by their legislative and executive branches.
In any event, I think you may have misread my post. I was not arguing that the current restrictions are likely to be held unconstitutional. But it is just plain inaccurate to say there are no constitutional questions presented by them.
