Strong lockdown is literally illegal in the US, violating freedoms that have been through the courts many times. It has nothing to do with selfishness. The government could never impose it, and they knew that. In the US many rights are near absolute in almost all circumstances, including the current ones.

You may disagree with those freedoms but they are a matter of law. They cannot be erased when they are inconvenient, it would render the judiciary irrelevant.
