I'm pretty sure that there exists no law forcing the holder of a
patent to allow others to use it.
There are no such laws. Though the government has in some cases forced the licensing of patents, e.g. some of the intergovernment deals on AIDS drugs, and earlier the Wright patents for military aviation in world war I.
And even if there was such a law, it's still the decision of the
patent holders, what price they demand. They can exclude everyone by adjusting the price. And there's no reason why they shouldn't define different prices depending on who wants to use the patent...
Differential pricing is tricky, any such scheme can easily run afoul of anti-trust laws. So the claim of "no reason" here is dubious.

I agree, but while admitting that not being an expert, I'd like to add my thoughts:
1) Secret, individual negotiations:
I agree that "defining different prices depending on who wants the patent" is not something somebody would do in the open, but I think the licensing company can always just do individual negotiations under NDA so that no one gets to hear the price and what has been discussed in the negotiations.
Such price could be easily get lower or compensated by cross-licensing, so there is some advantage in being able to cross-license when opposed to not being able to take part in such deal.
(e.g. very small Linux distributors like Mandrake and Conectiva likely would not have the possibiltiy to do effective cross-licensing)
IMHO, patent pools(I think of MPEG, GSM, UMTS, G3 phones) can be seen as very closed clubs to which an outsider without much money likely has no possibiltiy to enter and where there is IMHO no transparency of the deals going on inside.
2) Licensing policies:
IMHO, licensing policies like Microsoft's FAT which cap the license fee at a fixed amount could be of drawback to smaller companies.
