Back of the envelope tells me levitating a person would need a magnetic field 10x that of this frog droplet, or about 160 T. The magnetic pressure of a 160 T magnetic field 1.5 million psi, or about 100x the pressure at the bottom on the Marianna Trench, and also about 1/3rd the detonation pressure of military high explosives.

That sounds like a much more convincing explanation than “we simply don’t have this material”.
