And why was his argument faulty in your opinion?

He claims the materialist position is that conscious activity is directly correlated to the amount of neural activity. I don't think any actually says or believes that, so it's a strawman.

A great deal of brain activity is repressive/controlling. So it's no surprise that if LSD reduces the overall level of neural activity that the conscious experience of a person might be greater(whatever that means).

Also it's not just a reduction in neural activity it's a change in neural activity with there being an increase level of activity around signals moving between different regions of the brain.

That's not true, proponents of IIT propose exactly that, or at least heavily hint at it, to them the richness of conscious experience is directly correlated with the amount of "integrated information", and it's not really an unresonable leap to assume more neural activity would lead to more integrated information, so no it's actually not true that physicalists don't believe this.

And again, if you don't believe it to be so you're supposed to show a concrete competing theory, not just gesture vaguely at a potential future theory. You don't really have much to stand on yet you keep pretending like you've basically figured it out.
