I'd say if you pulled your shock boots and they were loaded with dirt or water, they must not have been sealed very well when they were installed. A tiny bit of dirt may enter through the drain hole, but that should be of no concern. The first wiper seal will take care of it.
It's the dents and dings on the piston rod that will waste your shocks. Even tiny ones. Small gravel and pebbles can damage the rod surface.
I suppose the super mod rock crawlers that are trailered to the trails wouldn't be subjected to the spray of rocks thrown up under the rig at 40 mph on a gravel road. That's where shock boots do their job, not creeping over an obstacle.
So maybe if I WANNABE like the super mod rock crawlers and go bootless, pretending like I don't tear a** down a gravel road from time to time, that's cool. It is optional...
