Use the same trash compactor theory on a bag of dense bud and you'll get the same results: a bag of compressed buds where the percentage of resin by volume has gone up according to how much you squished it. Are you really asking why compressing Mexican weed for transport doesn't turn it into dank...?
A small dense bud can have just as much or more surface area as a bigger fluffy one, it's just in more compact layers. As each new calyx piles onto your plants, don't they each have their own bed of resin? It doesn't go anywhere as new layers grow over it, it's still in there when you peel the layers away to smoke it later.
It seems that the poll should have been "Who prefers not to grind their stuff before they smoke it?". I'm almost exclusively a joint smoker, and I'm not about to just roll a paper around a bud and lick it, fluffy or dense. The dense one would be like trying to smoke an acorn and the fluffy one would probably tear my throat out. De-stem it and grind it up nicely first and it will burn like a cigarette.
You're pretty stuck on something that is just a personal, somewhat underdog, opinion. It's also pretty strain dependent. I couldn't care less, smoke whatever you like, it doesn't affect me. I just don't know why you seem to be looking for converts.
