Doesn’t this commit you to the claim that at least some beliefs about whether or not a particular Turing machine halts must be meaningless? If they are all meaningful and your criterion of meaningfulness is correct, then your simulating computer solves the halting problem. But it seems implausible that beliefs about whether Turing machines halt are meaningless.
