While there is a real risk that cryonics organizations will fail, there's no reason to think it's a foregone conclusion. Tons of organizations have been around for over two hundred years. The oldest non-profits in continuous existence are well over a thousand years old. There's no legal barrier to a non-profit corporation or trust continuing to exist indefinitely, as many indeed have. (Heck, the Nobel Prizes are an after-death trust that has only gotten larger and more famous in the 122 years since Nobel's death.)

The only regular maintenance needed is adding more liquid nitrogen, and the storage dewars can last for many months before replenishment is needed.
