Because Allah allowed it for Him and did not make it halal for us. We should never try and reduce the marriages of the holy Messenger to political reasons or because of circumstance.

The Prophet was the most just and Allah fearing amongst us, he was never unjust to any of his wives.

The Prophet loved all his wives dearly and this love was reciprocated. Naturally being human they would be jealous of one another and they would try to compete in their love and attention of Him.
In this inter-wife rivalry they would boast and brag with one another; subhan Allah these narrations are beautiful and offer an amazing glimpse into the personal life of the Prophet Some of which are very humorous and witty, whilst others are very serious.
Our mother Aisha was extremely beloved to the Prophet , and no doubt when she got involved in these rivalries she had the ability to silence the others; not just because of her love for the Prophet and vice-versa, but because she was very eloquent in speech; in fact not too dissimilar to her father Abu Bakr.

On one such occasion Aisha said something whereby the other wives were silenced and they could not think of a reply to her. The Prophet observing this simply said, 'Afterall she is the daughter of Abu Bakr'.

Treating someone differently is not always the same as being unjust or unequal, and certainly this was not the case with the Holy Messenger and his wives. We can be equal but we are not identical.
