Many of Charles' ideas were not bad, but they weren't practical either. He could propose stuff like treatment through natural means because he had the knowledge, but with hundreds of thousands of guests visiting the recovery room every day, it was impossible for him to take care of all the guests.
He could begin teaching others his own knowledge, but that too would take years before it yielded any real results. As such, there was no real way to implement all his changes right now. Some of them, however, were not so bad and could be implemented immediately.
For example, the lifestyle adjustment for the Inn workers. He always knew that they weren't 'born' naturally since the Inn created them as and when he wanted, and he could even pick stuff like their bloodlines. Such topics demanded some philosophical questions such as the ethics of cloning, and if what Lex was doing was right or wrong.
