I have google accounts that I created a decade ago but I can't remember the last time I logged on one, except to log on gmail and clean the box in private browsing. I basically only keep them because I used my real name and don't want anyone to steal an account/personnal info I might have created with that gmail address and impersonate me. I don't really see what is difficult in operating without a google account.
