I think that juxtaposition alone makes this a relevant discussion topic, political associations or not.
Regardless, even if it elicited some response in him... being a modern billionaire usually requires stepping on lots of heads, being ruthless and very self-interested. So I think it wouldn't bring someone like Musk a whole lot closer to the rest of us.
To your point, maybe it’s a good argument to not have billionaires that are seemingly ignorant of the normality we normals face on a day to day basis, be an influence on policy that they lack the ability to fully contemplate.
Such individuals might just consider policy based on data points that aren’t reflective of how their policy changes might affect everyday folks.
