The fees are like 3 bucks. The answer is to just spend more money? How is that sustainable in the long run?
Hypothetically, let's say bitcoin takes over the world in ten years: the fees will be astronomical. At some point "just spend more money" is no longer a practical solution for the majority of users.
Opening a small channel doesn't make sense. Channels are meant to be used more than once. That's the whole point. If you have recurring purchases, you can open a channel to save on miner fees.

It would be interesting to see a calculator that could estimate profit based off channel size and fee settings.
