I read all of the above and no one refers to rising fees.
I see the highest stretch of fees ever has occurred in the last 13 months. see below

those number will grow after the ½ ing
and as much as they do this time.
in 2028 even more.
Latest increase of transaction fee, mempool congestion mostly come from Ordinals, Inscriptions, BRC20 tokens. Your chart shows that before this wave in 2023, Bitcoin mempools had two other times with high demands and expensive transaction fees, in 2017-2018 and 2021 because of two previous bull runs.
Fortunately, after bull runs, it was cooled down to nearly normal in 2022 before we had crazy contributions and effects from Ordinals. Demands on Bitcoin will continue to increase especially after each halving but about Ordinals, will they stay forever on-chain or will migrate to Lightning Network or some layer-2, I hope they will because it will help mempool and Bitcoin users.
