Forget about the official website and the documentation, it is filled with lies and misinformation.
For example "Individual satoshis can be inscribed with arbitrary content, creating unique Bitcoin-native digital artifacts that can be held in Bitcoin wallets and transferred using Bitcoin transactions." is filled with misinformation. The satoshis are not inscribed, the content is not unique and there is no way to guarantee its uniqueness, you also can not and do no transfer the content itself to anybody when you send coins.
Another way of looking at Ordinals is (to put simply)
a brand new scam method to sell tiny amounts of bitcoin to idiots at much higher prices.- First step is to come up with some arbitrary data which can be anything like byte presentation of a picture and create the Taproot script.
- Second step is to compute the corresponding address of that script and sending some small amount of bitcoin to it (eg. 10000 satoshi)
- Third step is to find some idiot who would pay a lot of money to buy 10000 satoshi (of course minus the fee so in reality in the example above they are buying 5920 satoshi) for a lot of money.
- Fourth step is receiving the money and sending them the tiny amount of bitcoin whilst revealing the garbage data you created in step one.
There are no NFTs, no arts, no ownership, ... being transferred here, individual satoshis have no extra value, ... and all the other lies they tell in step 3.
Bottom line is anybody who paid more than $1.28 for the example above is being ripped off while contributing to an attack on Bitcoin. Arguing over UTXOs and how they are involved in this spam attack is pointless in my opinion
