A very good point. I think the financing would be less of an issue, honestly; $200 billion a lot of cash up front, but spread out over five or ten years it's well within their FCF if they wanted to allocate it that way.
EDIT: As another comment pointed out, FB might also be able to convince advertisers to subsidize some (or all) of the costs of "free" headsets for the masses, if they wanted to try this scheme.
$200+ billion. They can't afford it. They couldn't get the manufacturing for it, either.
