I think you're underestimating the percentage of bricks in modern sets that can be described like this. They're very hard to mash up (e.g. "I'm going to use these two castle sets to build a totally different GIANT castle!" or "Now this pirate base is an oceanographic research center!"), to add on to, and to repair if damaged. Plus they're just damn tiny for the part count.

They do sell the buckets still, which is always the retort to complaints about modern sets, but it makes me sad that the entire way I played with LEGO sets when I was growing up is nearly impossible with (most) modern sets (the ones intended for kids, I mean—I don't care if the ones plainly marketed to adults aren't good for those things, of course).
