Ive made these bowl structures before. Not for a hammock but for a tarp. They'll hold a lot of weight for sure, you're right about the staking. Getting a good anchor in sand can be hard.
Here's how mine is setup today
I've been using the trucker's hitch. Tree straps to 6mm utility cord to trucker's hitch to one belay ring lashed to each end of the hammock.
Always use treestraps, cutting a ring in tree bark will kill the tree.
We're in interesting times, we get to see first hand how leftism always regresses. Give these blue haired freaks more power and next thing you know women will lose their right to vote and we'll make slavery legal again.
1/3rd of Americans are legally retarded, and most of the rest don't have the capacity to mentally model complex problems.
OFC they consume mainstream ideas. They're programmed to consume everything else in front of them.
The key is to break people free from The Great Lie.
