Julian Cope presents Head Heritage

Yes, but that doesn't disprove the fact that plenty of megalithic structures were clearly used for purposes relating directly to death/dead bodies.

I think you said you had seen no evidence the use of megalithic structures for purposes relating to respecting the dead, but there's loads and loads of evidence for exactly that, isn't there? Even one chambered long barrow full of bodies would be a good start, hundreds surely constitute proof, regardless of the fact that there are hundreds more that don't?

I'm not suggesting for a minute that all megalithic structures were death-aspected, just that there is fairly unassailable archaeological proof that some were.
