This is why scientists are mocked. You get some guys from materials science saying 'hey we can do this cool thing with beach sand and electricity' and they don't bother talking to the physical scientists about ocean erosion and why their idea does t make any sense.
They would tell you that beach erosion is inevitable. Either you let it happen, or you put a bunch of hard structures there instead. Then, the waves either undercut the hard structure, leading to more needed, or the wave reflection scours the beach and takes all of the sand out to sea or elsewhere along the coastline. Meankng no more sans next to you - just a concrete cliff.
Also sand is one of the most limited resources with actual cartels working on stealing it - and you want to use it as a primary building material? Instead of just a contributor like in concrete? What?

Yeah, the problem with seawalls isn't that they're hard to make, it's that they're even worse than doing nothing. The coastal area where I live makes it almost impossible to build seawalls, and for good reason.
Often something like this is published and people don't use the methods for the materials they are described with. It's like taking the idea to make dough for baking specifically shaped bread, and using the concept to make specifically shaped ceramics instead
