I don't agree with the comparison to "making" coins or cash.
Coins and cash actually get consumed as they degrade and/or get lost or destroyed. You need to replenish the supply.
But you can circulate bitcoin forever.
You need to compare transactions.
How do I send you cash? You can give me an address to meet you at. We both drive our cars or take public transit there and consume some amount of energy and time to meet up. Then I give you cash.
Or you could just tell me a bitcoin address to send to.
