That's just waffle, you can't say "they just built them".

Several machines are listed as being developed from suits like RX-0 Full Armor Unicorn Gundam, so the entire series of events that lead up to UC 0096 must have happened as well. Same applies for the machines developed from Epyon and ∞ Justice, they can't be "magicked" out of thin air without any regard for their background.
