The strawman is that Hamas is intercepting all the aid. Sure people occasionally say that, but you're attacking an oversimplification of the real underlying points, which are that

- Groups of men with rifles tend to be belligerents in the conflict, even if we can't say definitively if they're with Hamas, PIJ or some smaller gang. Israel doesn't want an aid program where the bulk of the aid goes to their literal war enemies.

- Even if some of them are "civilian armed gangs" and not actual belligerents, the aid they steal still isn't getting to civilians (except when it's sold at extortionate prices). Hence the shift to GHF which, while it has its own problems, does actually deliver most aid to ordinary civilians for free.
