You have to buy or steal the PoS coins to stake them?
Their is a cost involved.
Buying empty private keys will be very, very cheap compared to renting hash power.
True but stealing private keys or stealing control over a warehouse full of asics is closer to free.

Also your pretense at how easy it would be is over exaggerated.
Feel free to 51% attack zeitcoin to prove how easy it is for you.
(According to you it is a zero cost attack so nothing is stopping you.)I have no motivation, nor desire to attack your shitcoin, I have better things to do with my time.
Ah Ha!
See there you refuse to pay the cost of the time it would take.
So you admit it is not a zero cost to attack a coin as you are unwilling to spend your time on it.

You guys have a good day.
