I'll sign it for the simple fact that I don't think this "temporary" measure will ever go away. Much like income tax, a temporary measure stated to be a stop-gap measure for an even that affected many people, I think this will remain with us for life. Well past the lifespan of covid. The Government doesn't sink this much time, effort, and money into something just to reverse it in a short few months. If you need more convincing just look at the security measures implemented after 9/11.

Singapore has implemented their own vaccine passport and have already allowed their police forces to use it for location tracking for "crime fighting". This vaccine passport is a terrible idea and I won't be using it.
