Well, I found out why the blockchain is clogged up with so many UTXOs that otherwise seem to have no function... Ordinals/inscriptions. Examples (these two aren't bad, but a lot of stupid stuff being posted):

I would (likely) be against ordinal inscriptions, as they do seem to slow things down, and Bitcoin's blockchain's best and highest value is for moving money. IMO.
Edited for errors, geez that took a while...
