Bad argument. Since a fork could be pretty much interchangable, it would get traction in no time. All the extra hoops a user would have to jump through to use a token instead of ETH/BTC would drive first new users, then the old ones to the new alternative. With them, the node providers follow.

Unless you have good, technical reasons to use a token, a token approach is always inferior to a general money approach and will eventually be outrun by general money approaches. That's why we don't have Banana-Dollars to only buy bananas with, and Bread-Dollars to only buy bread with and so on.
The only thing a token might still provide at that point is the utility of a discount method. And that'll only work if you find node providers who are willing to play the game that way.

So, are there technical reasons?
