There's some merit to this argument. If your goal is to hurt China's competitiveness in spite of what it costs US buyers than its a legitimate strategy.
However, this policy is being sold as a way to help US manufacturers and that's not quite the same thing. The benefits could easily go to other imports with weaker tariffs. This coupled with the problem of hurting down stream US manufacturers means that the only benefit is hedging against a Chinese monopoly and not the direct benefits that are usually talked about.
