That's what gil is for - to skip content you don't want to do. Do you want to run expert 4 times to get a ring or do you want to pay a crafter 150k to get one. Do you want to get a pile of gold to furnish your house by running aquapolis 20 times, or do you want to pay someone else 3 million. Do you want to spend an hour gathering 40 fish for that food you need to craft, or will you buy it off a gatherer.

Personally I don't have any gumption to pay for a minor stat upgrade, but it ain't my gil.
