Yes, once everyone has had the opportunity to have had both jabs, then yes, it would be time to move on as far as possible.
But we're not there yet. Younger adults won't have had both their jabs until around September, so we can't open everything up until then at the earliest.
As for foreign travel, that will depend on other countries. Even if our government allow unlimited foreign travel, we have no control over whether other countries will allow us in/out of their country freely.
So, overall, I think restrictions, to some extent, will be here to stay throughout Summer. Once all adults have been offered both jabs, then we can have a rethink, bearing in mind the vaccine effectiveness against new strains. If it turns out that the vaccines are effective to new strains similar to their effectiveness for existing strains, then I see no need at all for restrictions etc from, say, September onwards.
Those who've chosen not to have their 2 vaccine shots will have to bear their own risks. If they're worried about catching covid, then they'll have to moderate their own activities to reduce risks to whatever level they are comfortable with. And yes, that may involve them having to give up their current jobs if they're not happy to work in what they perceive to be unsafe environments for them.
Once the vaccines have been offered to all adults, and as long as the evidence shows they are effective, then it's time to move on. We can't hold back for the benefit of the few who won't have the vaccine or who have medical conditions meaning the vaccine may not be effective.
