Fun scenario but you wouldn't make money or be on the tour for a long period just making the cut and finishing last. There are a few tourneys that don't have a cut.
Tourney fees
Travel fees
Caddie fees-Depends on golfer/caddie agreement. Majority get paid a certain amount per tournament whether they make or miss the cut. Plus if you make the cut they get a % of your winnings.
Lasting on tour means making a bunch of cuts with finishes all over the board or doing real well in a handful of tourneys if you miss a bunch of cuts. Also depends on the tournament and payouts as they vary greatly.
Just make sure you make a bunch of cuts, win one for me and lock up an endorsement deal
