What you are saying is that this particular year, without HB at worlds, USA would not lose out on a medal (because they are not really in the mix for the podium with some strong opposition coveting the 3 podium steps) AND the USA would not lose spots as it is very likely that C/B will finish top 3 and that the other team would finish top 10 and most likely better. So this would nullify the need to send HB to worlds via petitioning.
I think this analysis is correct (as you said, brain works that way, the heart, another matter) but there is one detail to consider. This is ice dance : In my opinion, the USA would lose out a lot not sending HB to worlds because in ice dance, momentum is everything. At the beginning of a new Olympic cycle, the rankings are somewhat shuffled. Having HB in the top 6 at worlds would seed them for GP season, would give them important ranking points, and if any of the current top teams were to retire in the coming years (many have mentioned C/B as well as both Canadian teams - could be retiring after a world medal or a participation at home worlds in 2024) ... In light of this, the USA would not be doing themselves a favour by not sending HB who could become "on paper" ranked number 3 in the pecking order for the 2025 season, very close to the olympics...
Yup.. .I know.... we are thinking ahead

but it's ice dance where momentum is so much more important than in the other disciplines.
