This argument doesn't work if you believe that not everything has to be type 1 fun- that is, we don't always need to be doing things that are pleasurable in the moment in order to be "happy".

For example, learning a skill to an advanced degree. Moment by moment it's not type 1 fun, but as you progress and look back, you realize that you've grown and improved. It -does- make me happy to see how far I've progressed in the hobbies/studying that I've invested a lot of time in. Conversely, seeing how much time I wasted doing "type 1" things all the time a few years ago makes me somewhat sad.

Consistently playing the slots [highly engineered products designed to be addictive] has to do with addiction and dopamine rushes when you get a hit. I wouldn't categorize that as the same as doing things like hiking or whatnot.
