This is simply a non sequitur. These optimizations benefit users. On
the other hand, asicboost doesn't benefit users in any way, it only
benefits some miners if and only if not all miners use it. It
obviously harms the miners that aren't using it by making them less
profitable (maybe to the point that they lose money).
If all miners use it or if no one of them uses it is equivalent from
the point of view of the user. In fact, the very fact of allowing it
makes the network less secure unless every single honest miner uses
it, for an attacker could use it against the network.

Even if asicboost was good for users in any way (which as explained
isn't), this proposal doesn't disable it, only the covert form that
cannot be proven to be used.

Therefore there's no rational arguments to oppose this proposal unless
you are (or are invested in):

A) A Miner currently using the covert form of asicboost.

B) A Miner planning to use the covert form of asicboost soon.

C) An attacker using or planning to use the covert form of asicboost.

Asicboost doesn't seek this and doesn't help with this in any way.
