Nothing was skipped - the point is that this is directly analagous to unscrambling an omelet. Separating mixed things is significantly more difficult than mixing them.
"The laws says X" doesn't change whether X is possible or not.

It’s quite literally not analogous as breaking up companies has happened a bunch but no one has ever unscrambled an omelet
