Earlier quoted context omitted.
Setting aside other ways crypto can and is being used, the most interesting thing about DeFi IMO is its compositional (and decompositional) nature. This mostly results in reinventing things that already existed in Wall St and other areas of the finance world, but are now available for anyone to use.
Can you give specific examples of these 'things' though?
It was exciting when I first looked at it and then I realized that this was actually not "democratizing" anything so much as ensuring a new class of folks would be able to create new centralized "everythings" in a new environment outside of the current system - without the benefit of the years of testing, regulation, and (sure) cruft that our current systems have because they're subject to political forces (which is actually a feature).
Maybe starting the wild west over again is a good thing? My money's on "not really" at the moment.
