Like you and many others who has written there - I do not believe that achieving of ubiquitous sexual satisfaction or getting practically unlimited free access to fulfillment of the sexual desires (if ever at all possible) will be-all and end-all of social development or in other words the “end of history”.
I also can’s see how universal happiness could be a achieved after any “world’s new order” establishment. And the sex main pleasure is probably the feeling that you get it not because of your social/ material status but because of the attractiveness of your own fine and lovely personality (smart and smartassness).
My personal opinion on drugs usage [out of medical institutions] is that they are generally devastating for all the humans. Rigidly conservative stance as it may seems.
But IMHO you misinterpret equal2u there.
Under “fundamental desire” Eeual2u (IMO) understands much more: innate human drives, instincts, urges, impulses…
Equal2u did not refer to any arbitrary chosen subjects (money, demo[n]s, kings, nobility, drugs, machines, etc.,); social processes and activities (work, war,) or let me say the fundamental aesthetics longings (for music, art or beauty in any and all of its random forms).
IMHO in that particular case equal2u is basically retelling Freud’s story about psychological individuals who are first of all organisms and that any organism acts to survive and reproduce. Accordingly any such individual/ organism is directed toward the said ends by its fundamental needs - hunger, thirst, avoidance of pain, and sex. (Breathing is not included because (a)/ some organisms do not breathe. It is true that some organism are not making sex as well but let it leave it for now. ; (b)/ for the time being there is no serious restriction to that resorse on the mother Earth 
In the common case (Sun-eaters excluded) only sex out of these 4 fundamental needs/ desires may be self-suppressed by / taken away from the individual without imminent death of the latter.
Permanent voluntary continence from sex will eventually cause lack of offsprings [invitro and the likes excluded] and yes - continuous privation of satisfactory sex relation sometimes may cause nervosity, frustration, depression, constant anguish, misery and the likes.[Debatable as it is No sex is no fun - but is it unhealthy?
In my understanding sexocracy idea is an attempt to radically resolve this social/ individual human’s problem. Why this is better from the simple legalization of prostitution, the OP already explained. He thinks that sexual service providers shall be valued and justly honored by the rest of the society members rather than scorned. (The truth is that irrespective of the whores’ class[y]/ whores’ actual social status, the ‘normal people with “decent jobs” generally do not respect those who are selling their bodies for pleasure.)
Indeed it (sexocracy) has much in common (but is not one and the same) with communism (cf. From Money to Labour-Time Computation; or the general principle: From each according to his ability, to each according to his need; meritocracy (Ability and skills for providing quality sex services being the most valued merit in the sexocratic society) and most probably many other utopia or partly materialized projects of social engineering. But it at the very least needs to be seriously considered as a theoretical alternative. The right place for any utopia is the discussion forum. Even if when it seems to be artificially created.
I also sincerely think that equal2u (while mostly making a joke with us) has demonstrated quite efficient defence of his position and there are (IMHO) several occasions when his opponents while claiming to be regarding human beings as much more elevated creatures (rather than reduced to brutal sex driven pleasure searchers – “Kriswest - turning it into a commodity and remove all sentiment”; “taking it away from a private intimate loving situation” .) – did in fact vulgarize and belittle much more HM the Human - compared to equal2u himself). It may be my wrong (misunderstanding) but several opponents of equal2u were saying that sex is driven by omnipresent human’s desire for domination; will for power and etcetera. ” Ascolo Parodites ignoring the extreme degree to which power is involved in sex”; Kriswest “Sexual actions are about owning dominating in order to prove dominance.”;.Which I believe is wrong. The same allegation actually goes with the statement that “Kriswest - At our core nature we are capitalistic/Imperialistic. Just look at family structures then apply that to society. “
