But I'm wondering if that really is what needs to occur before we consider a a state to be a complete surveillance state, if, for example, almost every home has some kind of device that can be exploited for surveillance, e.g landline, mobile phone, television, smart devices, laptops/desktops/tablets, internet routers/modems, smart meters, smart heating, rubbish collectoin etc?

I.e. have we opted in to in-home surveillance to a sufficient level to make mandatory surveillance almost of no use.
