Again you are laboring under the false impression that halacha says not to wear Techeiles.
Not true. What I’m saying is only on the tzad that techeiles is legitimately being suppressed. If Rabbeinu Yonah held, in his day and age, that it was improper, fine. But that is no raya to us bizman hazeh. So my point still stands — Rabbeinu Yona expected the reader to have enough common sense to understand that he wasn’t referring to a (perhaps from his perspective purely theoretical) different situation where halacha would indicate otherwise, which on the tzad to keep the statu quo, it does so indicate.
