Of course not, it's an insane argument. To end up with a decent retirement fund, say $1.5m, you'd need to buy 50k units and store them for years. Whether you could even get hold of such a large quantity would be questionable, but when it came to shifting them you'd encounter a huge liquidity problem as you single-handedly flooded the market and watched the asking price plummet.

I think the only feasible way would be to use them as retirement income rather than a lump sum, by trickling them onto the market at the rate you needed for your weekly income.
