on 23rd December 2012 was the 99th anniversary of the Federal Reserve, and 99 years is the longest period of time for a business deal - it has to be renewed after that.

This is completely wrong. (Except for maybe the 99th anniversary of the Fed Reserve. I didnt' look that up.)
There is no time limitation for a business deal/contract in general, unless the contract says there is. (Now the Statute of Frauds requires contracts that cannot be performed within 1 year to be in writing, but that's something completely different.)
The 99 year lease you cited to only applies to real property, and I'm not aware of anywhere in the U.S. that it applies. I believe it's used in Mexico, however.
Well... you mean that a gov can have a contract with a private corporation allowing virtually control the country and this contract would never expire?
It is a law and a law could be repealed I guess.
