Well, there are some very important differences. 1) It’s super well known what’s going on with SpaceX. Every investor should know that there’s a lot of good stuff along with some steaming hot garbage. 2) SpaceX isn’t systemic to the economy. If SpaceX and all its subsidiaries shut down and its investors got nothing back, it wouldn’t be that big of a deal.
This type of bundling is just what conglomerates do. Is it a good thing? Not really. Many investors also hate this kind of stuff and avoid investing in these types of companies.
On point #2, they are trying to do that right now. If spacex is fast tracked into the indices, passive investors via index funds will be forced into buying.
