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.

I'd like to see your evidence for the first claim.
The second claim is not as well supported as you might think. A recent Cochrane review published by The American Academy of Family Physicians (AAFP) rated "Reduction in Saturated Fat Intake for Cardiovascular Disease" as having Unclear Benefits with no significant effect on all-cause or cardiovascular mortality. This is based on randomized controlled trials that measured endpoints directly rather than LDL levels.

No, we know that eating less saturated fat and replacing it with unsaturated fat, such as those found in seed oils, can reduce your risk of CVD as much as statins.

We know, for sure, that eating less saturated fat reduces your markers that put you at risk of cardiovascular disease. Your study points that out. The problem with assessing cardiovascular mortality is that takes many many years to come home to roost. As your source points out, most studies were only 12-24 months.

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, much stronger than the association with saturated fat intake. Are you really suggesting that they might not be unhealthy?
