7. ETF managers that track an index aren't allowed to put discretion into what they buy. They offer much lower fees because they don't have to do any thinking, just executing on an algorithm.

8. SpaceX servicing the X/Twitter debt isn't really a question. The total amount of debt is equal to about one year of revenue at the moment, and it's under 3% of the expected market cap of SpaceX. It's less than a third of what SpaceX's IPO is expected to generate selling new shares to the public. It's a non-issue. On the other hand, the fees the banks will get for the IPO could easily convince them to support the rules waivers.

9. This is true of some passive investors. It is not true of pension funds (which are usually not passive) or 401ks or other tax-advantaged retirement accounts. It is likely to be partly true for any individual depending on how much of their assets is in a tax-advantaged account vs a regular account.

10. Yes to Texas. It seems like the arbitration part is likely to be true (SpaceX is certainly claiming it in the prospectus), but there is not the certainty of having a long history of litigation.

Returning to 2+3: The rolling up of all other private Musk companies into SpaceX certainly impacted the investors in those companies, and how much Musk owns vs other people. But the equity adjustments there would be interesting, not the debt.
