I suspect what alex is saying is that there are so many millions and millions and millions of people who are refusing the Investigational vaccines that if they were to try and prevent all those people going abroad via vaccine passporting etc then business galore would go out of business without all their custom. Hence passporting and similar measures are counter-productive. Same goes for the ridiculous system of having to buy approved Covid tests and pay for hotel isolation on return from holidays which can add £1000s to the price of your holiday. All highly prescriptive.
They seek to win by attrition. To force us into the RNA vaccines by removing privileges and freedoms. Some fickle people will fall for that but I'll warrant millions won't. It would be a shame not to be able to go abroad for sure, but nowhere near as bad as finding I've taken an un-fully-tested vaccine that affects my life in years to come.
I can happily find enjoyment and peace in just "being". Being in and around nature. Never leaving my country.
TBH the very fact that they would seek to force people to take the vaccines in such a despicable manner pretty much tells me all I need to know about them. Good medical treatments and solutions aren't pushed through aggression and attrition and coercion imo.
