Which means the set of "necessary FISONs" doesn't exist.

You need to define "useful".

 A FISON is useful if its removal changes the union.

So, you agree then that you whole concept of FISONs are not useful when you start from the infinite set of them.
OF course, the start of your problem is that your logic can't make that infinite set in the first place to work at removing any from the set.
Sorry, you are just proving your stupidity.
