Regarding your old people solution:
i think your intentions are noble, but such an operation is logistical nightmare, especially given the demographic stucture of the country. And, in addition to that, it's open-ended.

Vaccines are a solution to a disease problem, i'm sure you would agree (or have been in the past, C-19 mutates fast), so there is nothing illogical, in my opinion, that people in power, technocratic or not, are going down this road. Question is, how do you make a decision about safety? Science consensus, people with PhDs in biochemistry or shady corners of the internet? In my naivety i go with former. Chiefly because it's a tough job to doubt everything. Civilizations are built on trust, when that trust breaks, civilizations fall. I would like this civilization to last a little longer, and this is just pure egoism: i have a nice life.

Of course, i rely on experts (call it subservience, if you wish). So i am subservient when i board the plane, assuming that it has been serviced by experts. I'm subservient, when i drink the water from the tap, assuming good work by water systems experts. Same with food, OTC medicine, roads, you name it.

WEF:
i have never watched any of it, maybe you have some video or article handy, that would summarize your viewpoint?
