Standard single payer insurance is not identical to 'seize total control of ever living body in America'. I shouldn't have to point this out.

The attempts by the current republican admin to seize control of certain 'illegal' bodies has caused so so much harm, I'd agree there. But even operating at 10x the nominal level of the past and ICE still haven't been able to exert temporary control over a single American city that resisted them, much less everyone in America.

You should figure out specifically what you are scared of and deal with that, rather than catastrophizing about things that cannot physically happen on any near timeframe.
