The answer to everyones questions is to build a decentralized exchange....... Where traders provide their cpu to power the network in return for zero fees. There's already a few companies working on this idea, these exchanges which will allow people to hold their own btc on their client inside their own computer and trade with others directly with no middle man. A few decentralised exchanges are being developed and tested. Can't wait until one launches. Meta Lair will be the first decentralised exchange and I'm sure many others will follow using the same technology.
