You missed a key aspect. Ethereum's of 3 cents or so per transaction are not here to stay. There are plenty of layer-two scalability solutions on the rise and they pick Ethereum because it encompasses true decentralization. With the delivery of layer-two scalability solutions, DApps can take advantage of Ethereum's security and decentralized state, while not having to worry about throughput bottlenecks.

Check our 2key Network as it's possibly the most advanced layer-two solution and it properly takes advantage of the various Protocols, like Bancor, that already operate on Ethereum. Not to mention, their technology enables instant creation of nodes and acquisition of ERC-20 wallets with the mere click of something they've termed as Smart Links.
