Portability is incorrect. It matters not the fee. You can always wait and handle do it later. Or, you can simply set an amount of set that’s lower and wait a miner to pick it up and execute it. It can take days? Sure. It is a matter of time preference. But it is as portable as any other digital money, with the exception of digital fiat.

Divisibility is wrong. It can be a network update to add more decimal cases to Bitcoin. The deflationary nature is a feature, not a bug. Indeed 1 sat can eventually become “1 dollar”, but that can be addressed if the majority of the network agrees with it, now, making Bitcoin have more than the 21 million cap is a deal breaker.
