Why don't Taiwan and Sealand officially recognise each other?

It may sound ridiculous in principle, the island of south east China and a sea platform in the North Sea officially recognising each other. But seeing as Taiwan wants to be recognised as the real China even though it is anything but, and Sealand just wanting to be recognised as a nation altogether; surely though regardless of how preposterous it may seem to recognise each other but yet by being recognised by another nation claiming to be a nation it would mean official recognition by both sides. Though admittedly there is no realistic reason why Taiwan would want it to be recognised by 100 extra people and that of Sealand ignoring the worlds largest country by population to recognise that of its capitalist brother doesn't make sense either, it would nonetheless help both countries in regard to individual recognition.
