Most likely because PG or whomever else coded the site doesn't know how to use HTML with CSS, doesn't care to learn, and doesn't think it's important enough to learn.
People might down-mod me for that, but it's basically the truth.
Now, the only real benefits that Paul would probably consider CSS giving him would be the bandwidth usage (stylesheets are cached) and maintenance issue.
I can't imagine either of those two would be enough to coerce him into learning a whole new way of doing things.
I certainly think that PG is missing many more benefits by not coding the site properly, but from his vantage point, (and everyone else who would see learning css as confusing and pointless) it's likely that the risk/reward assessment is not pointing in favour of a tableless layout.
