My contention is that a $40,000 piece of carbon art that can be sailed off the beach with a dolly, where the conditions are mild is different than a beach cat. There are races like the 2 recent 300 mile races were the boats are driven right up on to the sand. That curved section of the main foils protruding from the bottom of the hull would be a problem in a hectic beach landing.
If the conditions at Texel were force 4-5 with a tough surfline, and on shore winds i think the landing would be tricky for one of these foilers. Even if you get through the landing, there is still the issue of sand getting in your fiddly bits.
Few owners of these high end cats would risk surf sailing.
