It is not different and we are permanently doing so by asking small oracles 
like hardware random generators, timers etc in our programs.

Yes. The point is that often the term "program" is ill-defined leaving

correctly understood it, Tom considers a problem regading programs of fixed 
size, while opponents attack him with the results valid for infinite cases.
