Because Condorcet is still better than nearly all implementations of first past the post. But I think the commenter is getting at instant runoff voting methods: https://en.wikipedia.org/wiki/Instant-runoff_voting
None are perfect but IRV is in use and effective. Tactical voting is still an option but at scale either obvious or difficult to organize without being obvious.
Why bother improving a method that is inherently flawed? You can chose 50 candidates but they are all stupid and corrupt that makes no difference.
Why not make the system more robust and go with liquid democracy [1] ? (yes, I know, many technical/security challenges to overcome, first)
