I don't think it is just about the fees. The scalability problem is also about time needed to process the transactions, which I think you should agree is equally important.

Another two things that need to be addresses are volatility and security. Volatility cannot be dealt with, it will come with the maturity of the market.
But the security is indeed the main issue at the moment and it is the most difficult problem to be dealt with as one community cannot by themselves control third-party applications and web pages.
