To be honest, the discussion started out as a hack so that we could use a 'company' to share health care costs rather than the exchanges. As the population in the Bay Area ages there are those who still like to talk about tech, draw on whiteboards, write code, and build stuff. While at the same time having accrued enough wealth such that actually working for someone isn't required. So we asked ourselves, "What are the good things about working at a company?" and the answer was smart people to exchange ideas with, facilities that you could leave "set up" while working on a project, and for some, an absence of interruptions by others. The "bad things" you don't benefit proportionally from your work effort, usually they want to own what you do and not let you share that, and if you take too many days "off" they ask you to leave.
From that the 'League of Extraordinary Engineers' was born :-). Basically membership dues covers the cost of the facility, patent filing, and healthcare, and as the patent portfolio grows (the 'endowment' if you will) those costs go down.
