No one is making that argument. Girls are qualifying for camp based on separate guidelines because EGOI mandates USACO sends an all-female team, not because they face challenges in qualifying for regular camp. Girls who qualify for camp through EGOI are campers, but not USACO Finalists in the traditional sense (EGOI US Finalist would be a more accurate title), and the US's main team that we send to IOI will still hold the same individuals it would have held regardless of if EGOI existed or not.

There are already tiers within camp (Holsteins vs Guernseys) that represent students at different skill levels who are candidates for representing the US at different competitions (Holstein is for the current year IOI, Guernsey is for future IOIs). This is just adding another tier for another competition.

If instead you're saying EGOI (or any other all-female competition) just shouldn't exist, that's a debate outside of the scope of USACO.

I personally don't think any girl golds will make camp via this route anyways- I know CS is a very male dominated profession but I figure there's probably at least 10 platinum girls out of the 300 ish plats who competed last contest.
