While that is true, that is true for our entire society. Big projects are almost never started nowadays by selling somethings else (unless its a direct replacement). Instead, what usually happens is that you take a bank loan that is secured by assets, in this case his stock. Or to put it short: pretty much any bank would give Jeff a 10 bn loan that is tied to his stocks, its simply not true that there is any problem there.
