It has to be extremely frustrating not having the freedom to travel, with the both of you so close to retirement.
The adventure you mention would be the trip of a lifetime and hopefully, by the time you're ready to sail off into the yonder, the restrictions that have been put into place will be lifted.
Dreams are ideas put into motion and not having a choice to do as one wishes has put many dreams on the back burner.
You mention vaccine passports, that's another issue that gaining steam here in the states.
They say that getting the vaccine is still a choice, but what kind of choice is it really if restrictions are being put into place for the unvaccinated that keep a person from living as they wish.
I'm hoping that by 2023, we'll be all much more free. It's hard to feel hope right now, but rational thinking has me hoping it'll all work out okay. The media has a way of making us feel worse.
It's NOT a choice at all - same with 'you can't work here unless you get a jab' - that's coercion. I can understand WHY - for example, in healthcare.... but still, I'm deeply uncomfortable with it from a freedom perspective.
