Let's say that I do everything the same, just with bamboo, which I am positive would fail horribly...
What thickness of bamboo would you need?

Let's go with the last ones and we will say 56" x 96" outer dimensions, 16" on-center on the long sides, 14" on-center on the short sides--44 poles just for the sides. Five packs: $695.
2x3s are $2 at Home Depot.
2x2s are $2.30!
2x4s are $3.62, making $1.81 per 2
Even using 2x2s and 2x3s, it would cost $94.60 for 22 of each.
Um yeah. That is a bit less.
