I’m thinking we all need several aliases. We can also use throw away phones and email addresses we use on library computers, or computers we buy second hand at Goodwill etc. that we use on public WIFIs.
I’m also thinking we all need to by older cars. The new ones most certainly have embedded in them an RFID device - they already use these at the production stage. Autos are required to be registered to a named owner, and so - instant tracking of any car owner.
