which means you cannot recover the original internal public key from the tweaked oneOf course. But you don't need internal public key, to move the coins. For example: what is internal public key here? As you can see, nobody knows, or uses any internal public key for some addresses, and coins are still spendable. Which means, that if someone will get the private key to the external public key, visible in the Taproot address, then it is all that is needed, to move these coins anywhere, under the current consensus rules. Of course, in the future, that may be blocked or restricted (so using untweaked keys is a bad idea), but now it isn't blocked, and it may never be (because then, there is a risk of confiscating some coins; it is a similar case, if someone would want to invalidate old, random P2PK, where HD wallets were not yet used). And claiming, that "all keys have to be tweaked" is a similar thing, as claiming that "everyone have to use HD wallets", which is simply not the case, when it comes to enforced consensus rules. Sure, having both the private and public keys allows you to do virtually anything you want. Regarding untweaked keys, they are from the class of exotic exclusions that some people try to fiddle with rather than being the general rule. Most wallets will not support this.
