Electronic money is never really yours, the government is just allowing you to spend it. When they need it, they will take it.
Once it’s all electronic they can then deny or retard your spending on certain things to gain your compliance. It might be determined by your locality, by region, by demographic or by your policital profile (based on your association or if you fit the profile of a dissident...or are suspiciously close -why chance it).
Electronic money IS debt.
all money is just blips on electronic ledgers. the paper stuff is just manifestation of the ledger entries
