I'm not sure it was even worth what I paid; time will tell.
Gore-Tex is not the most expensive because it is the most breathable fabric. There are plenty of others out there that are more breathable--heck Lowe Alpine was beating Gore-Tex breathability with their Triple Point Ceramic coating 15 years ago.
Gore-Tex is the most expensive because they pay attention to ALL the details.
For instance, as a membrane, Gore-Tex has to be glued to its face fabric. Coatings like polyurethane do not; they self-adhere. The type of glue, and how it is applied, makes a huge difference in the durability of a membrane-based waterproof fabric. Gore spends a ton of time and money on R&D around the gluing, which is why Gore garment manufactures must use Gore-approved seam taping machines. It's also why Gore can guarantee the fabric for life directly to the consumer.
Gore also reviews and tests the design of every single piece of clothing or footwear that ships with the Gore-Tex hang tag. Every company who makes a Gore-Tex jacket must send copies of it to Gore, where it gets tested in rain chambers etc. If it does not past muster, the manufacturer has to make changes until it does. As you might imagine, this adds cost. But it also makes sure quality is high.
