I like to phrase this differently. EVERYONE has a written legal will. If they didn't deliberately write and execute one on their own, their respective state legislature has a default will written for them. Most people who find out what their will says and it's implications, will choose to take action and write their own plan.
I guess this will also plug a bit the federal budget hole, as there will be a significant estate tax bill due on this one (presumably most of the wealth in shares of AMZN, which might create some selling pressure, but I might be wrong).
