You sure know the concept of incubation time. Barring infected persons from entering if they have no symptoms is not possible. And quarantining every single person who enters is also not possible.

Quarantine would only work in a society that respected the whole nearly as much as the individual, which you would know if you had been alive in 2020.

Who's going to pay for the quarantines - the same overburdened taxpayers you were concerned about?

I'm sure you would be happy and reasonable about being quarantined every time you travel abroad. You wouldn't complain at all.

Worked so well for covid

I'm not going to pay for quarantine. I'd like my tax dollars to go elsewhere, per your recommendation. Maybe you can make a charitable donation instead?
