Extinct Kits

I am trying for over a month now to buy any of these kits:

Arsenal

Manchester United

Juventus

Barcelona

Real Madrid

However, these kits are basically extinct. Any time I somehow come across one, it is already no longer available.

If there is clearly such massive demand for them, then why not simply increase the max price range instead?

I have opened countless packs as well and still have never packed any of the kits mentioned above. In previous years you could easily buy these items on the market, but now it is honestly harder to get one of these kits than it is to buy R9.

Also, what about historical kits, can we have them?
