I think you’re using a different sense of the word “possible”. In a simplified physics model, where mass and energy are easily transformed as needed, you can just wave your hands and say “there’s plenty of mass to use for computronium”. That’s not the same as saying “there is an achievable causal path from what we experience now to the world described”.
