Millions of people do play for high stakes, placing their trust
in entropy -- you know, real physics entropy -- and in procedural
safeguards such as clear plastic boxes.

Can you convince these people to trust a PRNG instead?

Can you make even a plausible argument that they would be better 
off using a PRNG instead?

And, by the way, where did you get the /seed/ for your PRNG, for
this application or any other?


As I have said before:  
   I can imagine a HRNG without a PRNG,
   but not vice versa.
