Actually, I didn't miss that at all. I even mentioned the fact that miners get fees in my comment. I know fees are high right now. What I am saying is that after all Bitcoin has been mined, miners will have to rely on fees for income. If transaction fees drop, it will be a question of whether or not the fees that miners bring in will be able to support the cost of their rigs and provide a decent profit.

I didnt't say mining wouldn't be viable. I just think it remains to be seen. We won't really know until it happens.
