Yes I certainly don't think your fundamental point is wrong. I don't think it actually fully clarifies the commenter's particular misunderstanding, but it is relevant and a good contribution.

To summarize where I think OP's confusion arises from: ionic "bond strength" figures are actually molar lattice energies and therefore reflect the strength of multiple bonds. Molar energies for covalent bonds reflect the strength of individual bonds. I've added a top-level comment explaining that point, which is how it was clarified to me in undergrad chemistry.
