Not nearly that simple. Have to apply for a lease of a site subject to very specific criteria, have copies of receipts for rock deposited, provide descriptions/samples of the deposited rock to the State, must demonstrate the rock deposited is distinguishable from any natural rock in the vicinity, provide the state with a bevy of other information including the percentage of lease area covered by the rock, and may even need to tag the rock. Then you have to pray a storm doesn't bury all or some of the rock in sand. Not the mention to the work, tools, and time involved in placing and harvesting the rock. There's no question it's hard work subject to complex regulation. There is absolutely a substantial amount of paperwork involved.
