Not to piss on anyone's chips, but absolute freedom? We're not getting back to that for months and more probably years. Until the entire world is vaccinated, as long as you let people in from elsewhere, as long as you go elsewhere, and as long as cunning new strains of the virus are working out ways to get round whatever vaccine happens to have been developed, there may and probably should be light constraints on the way people socialise with strangers. Emphasis on light, but they'll be there. I live in a country where prior to Covid everybody kissed each other on the cheek (men with women, women with women) or shook hands (men with men), as a standard thing. It's considered rude not to. I think there'll now be cautiousness about that for the forseeable future.
Oh and Pfizer, Astrazeneca, Moderna et al. have studiously refrained from guaranteeing the length of immunity even for such vaccines as we now possess. With good reason, since this has never been done before on this scale, and at such short notice. We're in uncharted waters.
That said: by God I would love to do something as simple as sit at a café terrace and have my coffee while I watch the world go by, or go into a pub and have a pint. Even if I do have to keep my distance.
