No personal offense taken, and the first thing on my agenda once I figure out how to source the material of size on my budget is to build (carve) a full-scale model of the wing from styrofoam. A material type similar to toy foam gliders[0]. Using the academic research for the proprietary design and the following guides, there is a lot of math involved and resources to incorporate:

Determined number crunching in the design will guide the dimensions and shape of the airfoil as much as I can humanly do with accuracy. However, due to the higher lift coefficient and lower stall point identified in the approach, there's some wiggle room I hope. I work a lot with my hands, do frequent sculpture projects, and have a basic mechanical aptitude.
Later comes the decision of the material / approach to construction of an actual load bearing unit (spar and canvas or composite molding technique) and adding control surfaces, with associated electronics. Likely sourced from RC industry. A couple close associates that would consult on this have background in RC and UAV development (pre-consumer interest), small-scale electronics (Pi, etc), associated coding work, and some experience with making composite (carbon fiber) type parts.
After watching years of the Moller Skycar hype[1], attempts at satisfying road and flight worthiness with flying cars, the Hoverbike[2], and the Martin Jetpack[3] I can totally understand the notion to think of this concept as vaporware. As you mentioned, physics doesn't welcome humans flying through the air. What present technology offers though - in materials and computing power for stability controls in extremely small Moore's Law packages and this academic research - is quite an exciting time to consider new possibilities.
To me, I think it should be an obvious 'given' that creating the wing unit as a tow-flight recreational idea will work, simply because mouting it to a pickup truck and mashing on the gas will provide plenty of thrust. It works with parachutes and boats - a seriously inefficient drag system - so while orders of magnitude potentially more dangerous, I don't see why the tow-flight implementation won't work as described. It's from this development that the next - powered flight - would be considered.
The amount of testing and development that this requires before putting a human on it is a genuine concern. Then again, certain types of people put on wingsuits[4] and jump out of airplanes or cliff tops. From time to time I wonder if I'm genuinely both smart and crazy enough to really put my mind to building it...but if I get started...no turning back!
