This is not a novel concept. When courts review laws made by Congress, they don’t get to second guess Congress’s economic reasoning. Congress could ban interstate transportation of beer on Tuesdays. As long as the law was within Congress’s commerce power, courts don’t get to second guess the rationale for the law.
In particular, Section 338 requires a factual finding (from POTUS, which is not directly reviewable) but then also tasks USICT with "ascertaining" the facts. It doesn't explicitly give USICT ability to review the factual finding, but it's a very plausible argument that if USICT is tasked with ascertaining facts and those conflict with POTUS's declaration, then POTUS is exceeding statutory authority.
338 has never been used and it's not clear it'd pass Constitutional muster to begin with.
