Floating Tent's May Be the Dumbest Invention of 2019

Floating Tents.  Yes, they're apparently now a thing and why they are I have no idea.  If you set up on a river like they show in the video below you're going to end up hundreds of miles away from where you started.  Even if you do this at a lake do you really want to row a hundred yards back to shore first thing in the morning?  I nominate the floating tent for the dumbest invention of 2019.
