The beauty of capitalism is you have a choice. There are already ETFs that exclude SpaceX/Elon's company's for those who so desire.
See QQNE and SPNE.
In practice the choices tend to be limited for a lot of the people for whom this rule change was meant to ensnare their money because it exists within 401k plans with limited portfolio options.
Right but that's because you've now layered in government control. 401k plans are more heavily regulated, often negotiated by the employer rather than the employee.
The real question is why are employers able to limit employee 401k investment choices and employee health insurance. This is not freedom.
