Are you sure you want to say it that strongly?  After all, if you
have a data set which needs always to be returned in the same static
format, why not just denormalise it?  It's sure faster that way in
every system I've ever encountered.

It's only when you actually have relations to cope with that it
ceases to be an advantage.  So, as usual, it depends on what you're
trying to do.
