That is a very silly way to base a coin's potential value, transaction fees handle that cost automatically more transactions higher cost, but more transactions higher coin usage if anything you just point out with it that doge is used more often and by more people than all other coins combined. How is this a bad thing?

That article is just an opinion. It's like me telling you that dinosaurs never existed because I can dig up an article that says so.
How is the fact that the amount of money needed per day to keep the coin at its current value an opinion?
It is a fact, however it is ALSO A FACT that doge has one of the biggest communities hence a lot more pull to attract new funds.
When the block rewards get chopped a few more times....doge will go up again, you can count on it. Yeah it just went from 20's to 200's so that is a pump and is settling back to a reasonable level...however in the future if you think 200 is the top you will be wrong.
