Where will they spend their sats if merchants do not accept them?

When merchants demand sats and refuse political currency, the only way a consumer can get the goods and services they want is to pay with sats. The consumer must acquire sats or spend from their stack.

As long as people have political currency and sats they will hodl their sats and spend their political currency before it loses more value.

When Washington was at Valley Forge, the army was starving because they had worthless political currency and local merchants only accepted hard money, in this case, British or Spanish coin.

The coin was mostly Spanish, as Britain tried to keep their coin on their own shores as much as possible, depriving the colonies the ability to build and store wealth.

Merchants will drive adoption.
