Reasonable thoughts. Folks have been arguing about this forever. Both sides - community-focused and individual-focused -- have reasonable points on the ethics and morals of what they claim. Both sides want claim to a split of the pie produced by the efforts of individuals.

Just like you're mentioning Obama's lambasted "you didn't build that" comments -- his point was completely valid, in that the individual profiteers didn't build the roads their products ship on, the energy infrastructure their cloud providers consume to host their digital footprint and logistics, etc. etc. But people pay for a large part of what they DO consume -- the cases where they don't are what we squirrelly and bookish economists call "externalities" (costs of production gotten too cheap/free). Trying to correct for every externality is a maddening and endogenous exercise in navel gazing -- but huge and easily seen externalities are not crazy to want to address (e.g., Erin Brokovich, pollution, etc.).

In your example of someone getting hired to field support tickets -- if that person weren't hired, the founders would spend all their time chasing down those tickets. So did the founder earn the cash, or did both people earn the cash despite one of the jobs being less favorable? If an egalitarian share is unwarranted, what is a reasonably fair trade? Why is an egalitarian share unwarranted? Etc.

The core question embedded in all these arguments are - what is a fair tax on the economy? If a government's policy encourages large economic growth for everyone, then perhaps it is good to fund it via tax with all the associated tradeoffs like crowding out, marginal decisions impacted, and so on. Getting it right looks like Scandinavia. Getting it wrong looks like Cuba / final days of the USSR. Ignoring it (on both sides of the aisle) looks like Venezuela and Argentina.

But there is no doubt that without the people who produce there would be no taxes, and a 100% tax would push everyone away from doing anything. This is why the way-too-simplistic Laffer curve argument seemed compelling in the 80s -- "unshackle the economy by lowering taxes."

I haven't kept up with pg (fairly or unfairly) since some of the techbrokings adopted Yarvinism as a goal, so I have no idea what he has said recently.
