I don't think I'm actually 'in' this experiment, but I do have my garden in. Such as it is. IT looks like Fort Knox. Everything is wired and netted and wrapped. As for being aesthetically pleasing, nope, not even a bit looking like that. I have black garbage bags flapping on poles to act as scarecrows. There is nothing attractive about a black garbage bag, no matter how you present it. (maybe I should add a bow made of dried grass and some pinecones?)
This year I tried to invent my own seedtape. Using flour and water made a paste and glued spinach seeds to a length of toilet paper, at intervals where thinning would not be an issue. Buried this in a trench, covered, watered. This does not seem to have worked. The toilet paper floated up out of the dirt with the next watering now it looks like someone used my planter box for a toilet. Withered bits of toilet paper here and there. Ick. And I don't think those seeds germinated. Maybe I used too high of quality toilet paper?
But all my ghastly expensive gladiola bulbs have sprouted. Hope deer don't eat them since there is no way to wrap them. Peas up, squash up. Tomaotes planted but looking grumpy. Good old nasturtium seeds popping up. Gordon bless the nasturtiums.
Oh..Sweetened, about burying a shipping container..they are very strong to weight from above, but not so strong to weight from the sides. A buried sea can would require heavy duty reinforcement on the sides to withstand being backfilled against. It can be done, but with extra oomph added. Have you seen where people bury a bus in a side hill, leaving the door exposed and use that as an undergroud bunker/container? The whacky things people do!
