The thing is, one can't fight the government. If they choose to make it compulsory, nothing stops them from asking for proof of vaccination when making transactions in the bank, or asking for one before you get treated at the hospital, or even during a routine stop and search while driving your car. If they want to make life unbearable for those who choose not to get vaccinated, they can. People will protest, but when has that really changed anything?
I just don't get the point of all the sneaking around. I only hope that the government has no ulterior motive for all this. Because it can do easily get out of hand.
