It isn’t clear at all how refining oil makes it materially “worse” in terms of health than the unrefined equivalent. That claim lacks both evidence and a mechanism of action.
Every argument I’ve seen demonstrates a pretty fundamental misunderstanding of the chemistry. These same bad chemistry takes are repeated everywhere by influencers. This isn’t unique to the oil discussions, dietary health is rife with vibe-based chemistry takes that are obviously unscientific.
Among other mechanisms, refining removes nutrients and other beneficial molecules, while purifying taste and reducing volume making it easier to overeat.
But the worst part isn't refining the oil itself, but the use of these oils in ultra-processed foods along with refined sweeteners, colorings, and fillers. Even if refined seed oils themselves aren't harmful, avoiding them is likely to be beneficial because it leads to avoiding ultra-processed foods.
Colorings and fillers are not that bad for you. You, and other, are missing the forest for the trees here: diets high in fat, sugar, and calories lead to heart disease and metabolic syndrome.
Replacing "seed oils" with hamburgers and french fries fried in tallow won't magically help your health. If anything, you would die quicker from the huge amount of saturated fat you're now intaking.
Ultra processed foods are bad generally, yes, but not because they're processed, but because they're high in fat and sugar, while being calorically dense with no nutritional value.

Should we cancel vaccines and water purification while we're at it? It's not hard to come up with vaguely plausible reasons for why those are bad as well, eg. "hygiene hypothesis", "gut microbiome", or whatever.

It's ironic you cite ultra-processed foods, another category which has questionable rigor and applicability, but people nonetheless defend because "Even if ultra processed foods themselves aren't harmful, avoiding them is likely to be beneficial because it leads to avoiding unhealthy foods."

The evidence that ultra processed foods are harmful is quite strong. Are you really suggesting that they might not be unhealthy?
