Keeping a record of everything hapening in the world in every nodes is not needed. (even stupid) You don't need this security level for day to day tokens, just for the base money you will use to convert from time to time to buy tokens

Shows a fundamental misunderstanding of what the purpose of a ledger is.

Nobody cares that a billion people bought coffee today.

Everybody cares that those billion purchases were not allowed to inflate the money supply.

So? Everything on the same ledger? Herp.

Seriously. Why do people think that anyone wants Bitcoin to be the only money in existence? Centralized systems work fine for local currency, whether it's coins and notes or debit cards from a local payment processor. Those are the only "sidechains" needed. Material scientists are developing technologies to make non-counterfeitable local currencies. Off-blockchain services can consolidate Bitcoin transactions. Bitcoin only needs to be used where it is beneficial.
