"this time it clicked more with me" Glad to hear it. Bitcoin in the real economy requires quite a different thought model, not "gold producer" for M0 but "circular trade finance" for M1.

"they turn it into colones" Exactly the sore spot. Sellers do that because - for all their faults - colones capability includes a Wage Fund for the earning/spending paradigm.

In a full Bitcoin system the sellers at the Uvita market accept bitcoin and then don't exchange it for colones but they redeem the bitcoin-denominated bills of exchange which paid for their merchandise on stock. Circularity.
