does it really matter that much? if we are going about our everyday normal life let TPTB waste their time taking our photos, if we are all on DVLA and tax systems and benefit systems anyway there isn't much we can do about it anyway, unless we drop off the grid completely and go and live in the woods we are on the system whether we like it or not, I don't know about you lot but I am instantly recognisable, no "grey man" me!!!
post SHTF is a different matter entirely.
Some people that prefer to be alone arent anti-social they just have no time for drama, stupidity and false people.
