No nation state actor is going to waste a 0day on a random nobody. Even the recent Notepad++ exploit was only used against specific political targets. Any actor smart enough to be able to have an arsenal of 0days at their disposal is also smart enough to use them only where they are worthwhile because they will only get to do it once.
Believing you are more under threat from sophisticated government hackers rather than unsecured IOT devices, unvetted npm packages or hijacked download links is just LARPing for people who want to sound more important than they actually are IMO.
