Ok, I believe you..

As you are such a pro on POS and Nothing at Stake, you might be interested in this...


***
Some rigorous research into POS, which includes some findings relating to the so called "Nothing at Stake problem" has been published >>> https://bitcointalk.org/index.php?topic=897488.0

You can play with the models used to get the findings yourself. There is still some questions to answer (which will be done in subsequent papers) but the authors found "it's nearly impossible to attack a proof-of-stake currency with '1% stake even' as stated by Buterin".


Please comment in the thread >>> https://bitcointalk.org/index.php?topic=897488.0 to hopefully get a good quality discussion going for the benefit of the crypto scene, let's leave tribalism at the door.

I am sure everyone would like to hear your theories on what makes you say "some people think you need 51% of the supply but this is bs, you need only a very little % if you just want to do a single double spend." The two PHDs who wrote that research say it "nearly impossible" to do what you say is trivial...
