Being required to agree on something in advance with your prospective spouse would be different from agreeing to go with the default. It means learning a bit about what is standard, and putting some thought into whether what you want is different from that. It would also remove the negative signal of asking for a prenup: if everyone is required to talk and agree on something, then you aren't doing something that indicates low confidence in the success of your marriage.
