Does Blu-ray HAVE to equal high definition?

Yes it would haha. Do you not see all of the compression artifacts DVDs are covered with?

But yeah, in addition to what has already been pointed out, season sets are able to sell at high prices because people see multiple discs and feel like they're getting value out of it. If they put 30 hours of content on a single disc, people will be less likely to spend the high prices on it, because in their minds, it's "just one disc" and "one disc is cheap to make so it should be cheap for me to buy!"

It's perceived value. It's the same reason why so many movies sell "special editions" with multiple discs when they could, in reality, put all the content on less discs.
