are re-buy tournaments as dumb as they seem to me?

[Adam22]

they seem like a way worse deal than freezeouts to me because to be on an even playing field you have to invest a lot of dead money that doesnt go to the prize pool. is there any real value to playing rebuy tourneys aside from when there are a very small number of players compared to the gauranteed amount ( since tourneys with gauranteed prize pools seem to be the only reason that a rebuy tourney ever makes any sense )?
