We made very good experiences with a realtor when we bought our apartment. Where I live, there is a lot of bureaucracy at play and the process is not easy to understand even when you have experts to ask. There have also been very sophisticated frauds on both sides - sellers and buyers - that a realtor from a well-known franchise blocks.
Generally, I see no problem with competent middle men. They offer a service like any other service. If you want the service, you buy it, and if you don't want it you don't.

I’d be willing to bet the reason there is a lot of bureaucracy at play is At least in part because realtors wanted job security. Just like taxes staying complex because of lobbying from tax prep companies.
I'm a bit confused about the tax prep. There's tax prep companies and software in other countries, too, and the incentives seem pretty much the same?
Germany has pretty complicated taxes, but I think they don't seem to have the same tax prep lobbying?
(In Germany, the complicated taxes are partially there because whenever you change anything or remove a complication, some people who currently benefit from that weirdness come out and complain.)
Here in Singapore taxes are mercifully simple.
