Well, you're not wrong on many of your points, but let's talk about why Disney would not want to decrease their prices. And it's not so much a marketing issue as it is an operational issue.
Let's take the mouse ears, for instance. If Disney could sell an unlimited amount of mouse ears, then yes, they would want to try to sell as many as possible, thereby lowering the price. The thing is that Disney cannot sell an unlimited amount of mouse ears. For one, their shops can only sell so much merchandise. If they lowered price, likely their demand would increase. That would make their shops, and therefore, their checkout lines, even more crowded. How many people, then, would decide to give up on their purchases and walk away because either the shop or the checkout line is too crowded? And then if they run out of an item too quickly, or many items too quickly, without the ability to restock, then customers walk away not finding what they wanted, which isn't good for business either. Also, there's the overhead costs to think about. Their factories can only make so many mouse ears at a time. They get another factory to make more, but that would increase their manufacturing overhead. They might not find it worth it to increase their overhead costs just to sell more mouse ears. They have to find a balance in their pricing where they are not selling too few and not too many. Unfortunately, that means the price is high, higher than many are willing to pay.
When they do find that they have rooms that aren't selling or resorts that aren't filling, that's when they run promotions, similar to the ones you found through the European site. They get the higher-paying crowd, but then they can lower prices to fill those rooms. But if for the most part, they're filling those rooms, then why would they lower their prices? It's also not necessarily a bad thing for them to not fill every single room. They can take rooms out of the rotation if need be for maintenance and service, and they also have a few left in case of last-minute trips and for anyone needs/wants to extend their vacation. We had to extend ours a few years back because of a hurricane...here.

We also had friends whose daughter got sick their first few days in Disney, so they decided to extend the trip. Same thing with restaurants: they are mostly full, but they also have walk-up space leftover, or same day reservations booked through the app or found by guest services.
Basically, we like to think that WDW is our personal playground that caters to us, but in the end, they are a business. They need to make money. We also need to keep in mind that Disney does not have unlimited capacity and unlimited amounts to sell. Would decreasing prices increase demand? Absolutely. Would Disney be able to sell more and make more money by decreasing their prices? Maybe...but there's a good possibility the answer would be no.
