Are you reading the news coming out. Omicron will have less of an impact than the other previous variants and if we wait for the next one then is may well be worse than Delta perhaps. Do you want to stay locked down forever? They are not just opening up for those reasons you provide. At some stage you have to open the front door and step out into the world or you won't have any of things you need to survive as they won't be produced or manufactured anywhere. This is the modern society we live in.
