It's a donation that is deceptively framed in my opinion, bit of a dark pattern, but the product is fully open source so most give it a pass.

I've not looked into it but presumably it's because whatever web server framework they are using might not be as bug free and battle tested as dedicated web server application like nginx so by limiting the actual web servers exposure you are limiting the attack surface.
You are forgetting the arcane patterns we have to engrave on them too.
Worse they often report issues that affect them but still don't commit resources to resolving those issues.
They run their own full OS these days on under powered SoCs to cut costs. All so they can claim to be a "smart" TV until of course the flow of updates stops a year after manufacture and all the apps stop working. Then it's back to being dumb as well as being a massive security hole on your network.
That was a long winded way of saying you don't know what Jellyfin actually is or does. Mpv is a client, it only fills the role that the various Jellyfin clients perform and a better comparison would be against a heavier weight media player such as Kodi.
What you suggest works well enough if you have a reliable network link to share CIFS or NFS over, but what do you do when away from home on a rubbish link that doesn't have bandwidth to stream all your high quality bluray rips? You want transcoding in that situation.
Also, I'm a seasoned Unix sysadmin who knows his way around the cli and I can say with certainty this isn't for people who know the cli, it's for people who just want to prove you can do anything from the cli even if suboptimal.
If only that wasn't true if the other big parties as well.
Shall I assume you are still a big reiserfs user then?
Indusputable proof of ownership of what exactly? The expired domain the nft points to? Nope. Whatever the link once pointed to? Nope. You only have owner ship of that particular urls representation in that particular block chain which confers you exactly nothing else. Not much different to the state you'd be left in with skins in a defunct game as I said.
Sure, but your entry in the block chain that is just a link to nowhere isn't much more exciting that telling people about the cool skin you once had in a defunct game.
If anything, by not giving the money to big multinationals more of my money will be going into the local economy instead.
Fully aware and autonomous? Sounds like AI talk to me...
