Would not decentralized finance lose its core value by merging with traditional finance? Even though some people might be into this idea, i know for a fact that a lot of people would not feel comfortable participating with a supposedly decentralized finance but authorities have access to the system it might also just be too confusing to people decentralized finance is already confusing to others as it is but to merge centralized finance with it it begs the question of why not just make it entirely different or separate? Both has pros and cons but merging it would not attract more people, i believe
Merging decentralized finance with traditional finance will not make financial sense because they're two opposing sides, one is centralized while the other is centralized, they serve different purposes, and merging them both will remove their core values. If this is done it'll bring more confusion than good, so they're better off serving their purposes differently, cryptocurrency is better off being decentralized and banks activities are traditionally centralized, that is the way they were created to function.
