#Bitcoin:

Scarcity based upon network and economic incentives that everyone follows because of free will.

#ordinals:

Scarcity based upon the content directly uploaded upon the blockchain which clutters the blockchain.

#NFT:

"Scarcity" based upon storing a link on the blockchain to a provider. There is no scarcity. The only way this could practically work is when people are forced to play along with it.

#fiat:

No scarcity, they can manipulate it, take it away, you are forced to use it. Oh and $X trillion of debt.

Use your mind.
