First of all, who said the Uchiha couldn't copy those techniques? Just because they don't add them to their arsenal of regularly used jutsu doesn't mean they couldn't copy it if they wished.

Also most of the Uchiha weren't actually better with he Sharingan than Kakashi. Kakashi is noted to be exceptional with the Sharingan even among the Uchiha, with only the best of the Uchiha being better than he is.
