The National Nuclear Data Center says you're wrong. 4H, 5H, 6H, and 7H are unbound. Look it up.
My colleagues are able to calculate the binding energy of the deuteron, remember? You just don't like the way they did it. They did it using a complicated theory, and you don't like that because you guessed that all such theories should be simple.
You are also not able to calculate the binding energy of the deuteron. You obtained the number 1.6 MeV---not actually the binding energy of the deuteron---by manipulating the constants associated with an electromagnetically-bound object of your own invention which has virtually no resemblance to actual deuterons.
