Why would there be no demand?

Given two IP blocks doing the same thing, where one just works, and the other requires to assemble a team to write a driver, surely the first is more attractive, no?

In addition to saving the cost of developing the driver, it would be possible to test the IP block immediately with no investment, and thus feel immediately confident that it works and the final product can actually be shipped with it.

Ah, but there isn't an alternative IP block with a driver to pick. As long as nobody making IP blocks supplies drivers, everybody making them gets away with not supplying drivers. Once somebody starts providing competent drivers, everybody else will have to follow suit, as you suggest. But it's hard enough to do and a limited competitive advantage (since everybody else would copy you) that market pressures won't provide the activation energy.

Also, my impression is that you can't do much with an IP block until you fabricate an ASIC that includes it, which is a substantial investment anyway.
