Another aspect is the fact that smart TV apps are sometimes not as good as their desktop counterparts. For example the YouTube app on most smart TV platforms does not support viewing show notes or comments. So every time the person in the video says "link in the notes below"... you are missing out on that link. Another example: I like watching martial arts, both the UFC web app and the FloGrappling web app have additional features that are not found in their smart-tv-app counterparts.
Another big one for me, is the fact that in a desktop environment I have better multitasking and I can use browser tabs. For example if I find a Youtube channel I'm interested in, and I see a couple videos that I would like to watch, I just open them in a new tab. On a smart TV you would have to add them to watch later, then go to your library and find them, it's just not as immediate.
Another point is gaming, I am recycling old computer parts that I removed from my gaming PC when doing upgrades, these are relatively old parts but still pretty good, so you can run triple-A desktop games with pretty decent quality, whereas the type of games available for download on smart TVs are mostly just ports of mobile games. I also installed RetroPie which is quite fun!
Then there is hardware upgradeability. Recently I was thinking to add a faster CPU, and then the CPU that is now in the HTPC will go into my NAS since the one I have in the NAS is quite slow. You can't do any of that with a smart TV dongle, all the parts are soldered to the main board :-)
One more thing I like is that it's easier to watch content using alternative clients, for example I watch YouTube videos using the FreeTube app, on Smart TV platforms you might be able to find some alternative clients but the choice is more limited.
EDIT - rephrased some parts as they were not clear
That’s fair, if that’s what you want and if that works for you.
For most users however that would make the TV impossible to use with a regular, simple remote and thus be a major downgrade in user experience.
Basically what it seems like (to me at least) is that people who buy “smart” devices don’t want them to be smart in terms of having advanced capabilities. Rather they want the devices to be smart enough to do the right things in a simplified UI, allowing the user to get the same things done, but with less effort.
Basically smart devices are smart to allow the user to be lazy, dumb or both ;)
Yeah another way to say it is that I want my smart devices to be general computing devices. For example I've build my own NAS instead of getting something like a Synology or a WD NAS, I'm in the process of building a router/firewall using OPNsense etc.
I spend more in the short term but less in the long term due to the ability to reuse old parts etc.

ahah yeah I see your point.
