I'd define a large debate competition here as a 64-person king-of-the-hill tournament, and I'd judge it by one standard: does it reliably reward better argument? My strongest objection is that scale directly undermines that. With 64 entrants, rounds get shorter and judging gets thinner, so results depend more on seeding, fatigue, and snap impressions than on careful reasoning. My opponent may say size widens access, and that's fair. But access to a noisy contest isn't real opportunity. A smaller field with real time for arguments and feedback serves debate better than a crowded bracket.
