You can absolutely dump the traces somewhere and analyze them yourself. The problem is that this falls apart with scale. You are maybe serving thousands of requests per second. Your service has a ton of instances. Capturing all trace data for all requests from all services is just difficult. Where do you store all of it? How do you quickly find what you need? It gets very annoying very fast. When you pay a vendor, you pay them to deal with this.
