*shrug* Everyone has their own way to travel. Touring does not have to be about "going fast" or covering a huge number of miles from day to day. (It can be, and there's nothing wrong with that, but it doesn't have to be that way.)

Ultralight has some benefits, but some drawbacks as well. The equipment tends to be more expensive and less robust. You may be happy one minute that you didn't bring that rain jacket, and miserable the next because it's pouring out. Leaving stuff behind may make you feel like things are simpler, or may deprive you of a creature comfort that can lift your spirits at a critical moment.

Also, while piling on an extra 50 or 40 pounds will make a profound difference, 5-10 pounds isn't even noticeable. I mean, really, you're on a bicycle, not mountaineering.....
