Also, making something suitable for humans means having lots of empty space where the human can walk around (or float around, rather, since we're talking about space).
Are there any unique use-cases waiting to be unleashed?
Keep in mind economics is all about allocation of scarce resources with alternative uses.
I agree that it may be best to avoid needing the space and facilities for a human being in the satellite. Fire and forget. Launch it further into space instead of back to earth for a decommission. People can salvage the materials later.
This effect can be somehow overcome by exercising while in space but it's not perfect even with the insane amount of medical monitoring the guys up there receive.
It's theoretically possible for sure, but we've never done that in practice and it's far from trivial.
Every child on a merry go round experiences it. Every car driving on a curve. And Gemini tested it once as well. It’s a basic feature of physics. Now why NASA hasn’t decided to implement it in decades is actually kind of a mystery.

From Wikipedia:
They were able to generate a small amount of artificial gravity, about 0.00015 g
So yes, you need an effect 60 000 times stronger than this.
And you want that to be relatively uniform over the size of an astronaut so you need a very big merry go round.
Nuclear fission is also a basic feature of physics, that doesn't mean engineering a nuclear power plant is straightforward.
When was the last time you spun yourself around in a desk chair?

There is a lot of research, but it’s not as simple as operating under real gravity. Makes many movements harder and can result in getting sick.
