A lot of us wish we could; but in the UK it is illegal to leave the house for anything but food-shopping, a medical appointment or (limited) exercise. I don't think "escaping a police state" falls under any of those.
Afaik most European countries have a travel ban unless it's for work.
Minimizing contact and travel, together with masks and sanitation,is proven to work and currently the only solution- unless hey you have a non tyrannical alternative then please let me know
Few European countries prevent people from leaving the country for leisure or family visits. I myself have managed to travel a bit this winter.
In some places, ruling parties have complained that they simply couldn’t prevent people from leaving even if they wanted to, because freely leaving and re-entering is enshrined in the country’s constitution. The UK, Australian, and New Zealand prevention on even leaving the country is much harsher than in most other developed countries.
"Minimizing contact and travel" is not the only solution, just perhaps the only solution you personally find palatable. Keeping borders open and simply accepting deaths works for me. Deaths are bad, but a new wave of nationalism and wall-building is worse.
