I wonder how would I feel if I am on his shoes, and realized that my two pizzas worth a million dollars now. Haha. I hope I won't commit suicide.
At that time, bitcoin is less than a penny and nobody knows at that time that it will reach a high amount now. Do somebody knows that bitcoin will reach almost 20k$ in 2017? None right that is why Laszlo used bitcoins in ordering for pizza. Yeah I think it is a great loss for him until now but because of what he did, he created history in the world of bitcoin. 
That is greater achievement than buying a pizza that is worth around 75 Mil Dollars.
