Maybe that's his point.
Still look as a taxable event to me.
Fiat has nothing to do with it.
You can just exchange a car with someone for another car and it will be a taxable event for the "equivalent fiat market value".
That applies even to smallish things like i.e. bikes, books, vinyl records, etc... except noone cares about reporting those.
that's why i'm not agree about that : State have VAT (20% in my country).
I don't agree to be tax target for exchange flux.
and by the way, the State use 20% of the economy to finance ?
No ! They use debt !!!
that's it : State can not be represent more than 20% of the economy.
