The key difference here is 'trivially'. Adding lots (and we are talking about lots when you consider the number of nullable columns) of tables makes it much hard to query that data (especially if you also disallow outer joins!). And if you are going to prove me wrong with an example, at least use a table with lots of nullable columns instead of just one or two.
