> unable to raise the money
I think Nvidia could borrow or raise basically any amount of money if they had capital-intensive projects to invest in that would solve current or future supply constraints. Retained earnings are not the only way a company can invest in itself.
The problem isn't capital, its fundamental inelasticity of supply for semiconductors. Fabs (or capacity in fabs) can't be spun up or down quickly, nevermind cheaply.
