I think you understand the point perfectly well. You just don't believe that there can be a logical system better suited to a foundation of mathematics than first-order logic (set theory), simple type theory, or dependent type theory. You believe you will need to compromise, no matter which foundation you choose, so better just to pick your poison and get on with it. And I think pretty much everyone in the theorem proving space has that same opinion, so it is certainly a most reasonable opinion.
But I don't believe that the right logical foundation will make it harder to do mathematics on a computer than on paper, I think it will make it easier. In fact, I am pretty sure I have found that right logical foundation, Abstraction Logic [1]. I believe that it is indeed the best logical foundation, because it is simple and elegant (more so than any other foundation I am aware of), and it seems obvious that first-order logic, simple types, and dependent types are just special cases of it.
But a logic is not a working and proven system such as Lean + mathlib, so a lot of work needs to be done before my belief can be stated as a fact.
