We all know most governments hate things they can't control. They also hate privacy. So I started thinking. Governments have blacklisted address for other things like sanctions. Transact with those addresses and you are breaking the law. So lets say IFP does activate. What happens if there is a whitelist address that gets blacklisted by say the US government? It could make any miner mining BCH a criminal.
Now you might think this is far fetched but is it really? I can think of one perfect example of where this might happen: Cashfusion. I'm sure governments just love the idea of not being able to track coins because of this tech. Let's say the project gets whitelisted. US government decides the developers have committed a crime just like they did with other coin mixing services. They blacklist anyone dealing with known Cashfusion addresses. Boom anyone mining BCH could be committing a crime. If they are using a pool they might not even be aware they are doing it.
The IFP opens up so many cans of worms.
