It’s a model. Models have it’s use. It makes sense to model a computer as an ideal Turing machine. It doesn’t make much sense to model a human that way.
Nobody suggested modeling humans as Turing machines. The question was whether humans are Turing complete and you implied that they are not because they make errors. By the same standard, no physical device is Turing complete.
Making errors means not behaving as a Turing machine. It’s separate from limitations of memory.
Any physical Turing machine will make errors.
To the extend that it does it’s no ideal Turing machine.
Ideal Turing machines, being, y’know, ideal, do not exist in reality.
