I develop meaningful, mutually beneficial
relationships with people and entities all the time. They use me and
I use them. My job uses me to write code. I use it to pay my bills.
My friends use me for support and discourse. I use them for the same.
It seems that you're isolating the lwa as "parasitic" simply because
you perceive that they do in fact make use of vodosanti's energy. To
steal castenada's phraseology, in "making yourself available to
power", you are also used by that power. it's not a
hoarding-all-of-this-is-mine process.
This reminds me very much of discussions with pettybourgeois individualists on how all political parties are by definition evil mind-control cults. If the Revolutionary Party is an egregore which aims to focus the power of a mass movement, then certainly by making yourself available to it you are also used by it. This requires you to make certain compromises with your freedom of speech and action, so as to synchronise with other consciousnesses to unify the forces (RIP RAW). Just as you would do in any ritual situation, naturally.
But the mere idea of this is of course anathema to the modern consumer consciousness, which declares that the isolated monadic individual is - self-evidently - the only real reality and only total and complete intellectual "independence" (i.e. isolation) is acceptable. But the catch is that "your only weapon is those you work with" (The Redskins, 1986). The isolated consumer-individual has absolutely zero power to do anything real - just to masturbate to a different set of images. The question is whether you want to be part of a world-changing endeavour and a vessel for power, or if you want to be a Beautiful Soul Unique Snowflake Pure Individual Just Like Everyone Else.
Not convinced that our culture promotes isolation, alienation and paranoia as not only an ideal, but the highest ideal? A common complaint in customer satisfaction reports is that some poor consumer's experience was ruined because they could hear the staff having conversations. They didn't pay good money to be reminded that real people are doing the work. They paid money for the privilege of voluntary isolation from other human beings - of being able to have a private experience in a public sphere. Think on that for a moment - that consumer culture promotes collective experiences, but only to the extent that any participation in them must be totally individualised and monadic.
Marx's utopian vision was one where the collective no longer contradicted the individual. Oh, we are so far away from that.
