If I may be a pessimist, then I believe Gates and Fauci are speaking from a Federal-level mindset.  Meaning, the Federal Govt cannot force vaccines.  But who can?  Possibly the state govts, since many/most states give 'emergency powers' to Governors and forced vaccines are part of the powers.  Also inherent in a 'medical emergency' is the power of forced quarantines (not in one's home, but in military camps). 
.
...All of these would be extreme actions, but arguably legal, and I don't know how far some states would go.  If Trump gets re-elected, then blue states could go bonkers and enact the above...which would start a cινιℓ ωαr...which is what they would want.
.
A middle-of-the-road scenario would be the implementation of vaccines by corporate america (who, in large part, has enabled the 'mask mandate', by encouraging and agreeing with all 'health mandates').  This would be the "fascist" implementation of the vaccine/chip/medical records agenda, because Fortune 500 companies could require a vaccine certificate in order to have employment.  All Federal, state, city and local govts could require vaccines too...for "liability" purposes. This could very easily happen and quickly.
.
So those who "choose" to have the "freedom" from vaccines would suffer the economic consequences.  Now that most mom-and-pop shops and restaurants are out of business, destroyed by this covid shutdown, (and will never re-open) who are you going to work for?  Will insurance companies cover businesses who don't require vaccines?  Or if they do, will they charge a large fee or require an extra policy for "non vaccine risk"?  It really could get dicey.
.
On a positive note, if Trump gets re-elected, (and if he's not a globalist...a big if...), then small business could return to America, through bringing back manufacturing from china and all kinds of infrastructure/construction jobs that we need.  This could be an economic boom that would save the middle class and reverse the damage done by NAFTA.
.
Otherwise, as it is now, the middle class is dead, and we are now a socialist country with the "haves" and "have nots".  And the "haves" will all tell us what to do.  ...Until there is cινιℓ ωαr, WW3, and/or we die of starvation.  The future is not bright, humanly speaking.  Only Our Lady can stop this madness.
