I actually don't read Elon's comments like Fred does:
Elon Musk plans to sell ‘major’ stake in Tesla in ‘about 20 years’ to finance SpaceX’s Mars plans
The way I read those two tweets: he will sell regularly, and will use that for a few things. Financing Mars being one of them.
The 20-year horizon seems rather undefined as that what he intends to do with that. Retire?
