well, yes, none of the dnd setting people think like medieval people at all.

but i take exception to this idiocy:

fundamentally incompatible with the European fantasy typified by Lord of the Rings, in which no fellowship can alter the fact that Sam is by birth a servant, Frodo a gentleman, Strider a king, and Gandalf a wizard.

has this person read the lord of the rings? sam becomes a land-owning gentleman at the end of the novel. he actually makes it out of his class.

to be fair, he's the only one in the entire god damned book. there arent even many speaking roles for named commoners in there. sam, the gaffer, ted sandyman, farmer maggot, butterbur, gamling, ioreth. that's about it. the vast majority of these are in the shire portions of the book.

edit: i forgot beregond and his son! but he may be a minor noble who has lost their land but kept the memory, or he may be a commoner of ithilien of numenorean descent. i dunno.

Interesting take. I look at it as less “anti-medieval” and more anti-government. Gygax was a libertarian and it grew out of wargaming. Gygax just wanted a world where he could fight dragons and didn’t bother to do the world building of an economic or political system. I think this was more out of disinterest in the topics rather than as a political stance.
