This argument is bullshit. You still need rules. When your dragon drops a boulder on the party it is still a rule - a houserule created on the fly. And the odds of fucking up are much greater when you just make up stuff on the fly.
I think you're mixing up the idea of a rule and a ruling.
When a dragon drops a boulder, I make a ruling as to how much damage I think it should do. I'm not making a general purpose rule to define falling object damage, I'm just ruling on: "how much damage does this specific boulder do when dropped by this dragon?"
Ideally, that ruling is not something pulled out of my ass, but rather based on guidelines provided to me by the rule system. And because it's a handy table, I can have it right on my DM screen. No page flipping, no stopping the game, I just reference the table, and there's my damage roll.
But that ruling is only going to be particularly relevant should that exact situation come up again. The same monster is carrying the exact same sized boulder and dropping it. I don't think I have to say how unlikely it is that that ever happens again in the same campaign. Even if it did happen say 2-3 adventures later, even if the DM's ruling the next time is slightly different, it's just not a big deal to make me care. So the boulder happens to do "Medium" damage on the table instead of "high" damage.
Why is that such a huge deal that a harpy rock dropper in one adventure deals slightly more damage than the previous one? Are PCs even likely to actively realize the difference between 2d10+6 or 2d12+10? If your PCs are that into the numbers, then you probably should be wargaming, not RPing, since they should be focused on the story, not calculating the damage range they expect the monster to do.
To me, that's like the DM forgetting the name of a village the PCs passed through once two adventures ago. You just make up something new and move on. If you have PCs that are that anal about stuff like that, I'd consider finding a new group. It sounds like they're not very fun people to be around. If your group is that rules anal, maybe you really
should be playing Magic: the Gathering instead of D&D.
Rules are for commonly used actions, not special case nuances.
