You can be even greedier. Things like skipping Vinario and whoring Qum to afford all 3 banks + crystal refinery in chapter 2, not buying non-profitable investments that disappear at the end of chapter 4, missing the best results in some events by delaying certain investments in favor of more profitable ones, etc.You don't have permission to view the spoiler content.

All of those things could increase the total ProN earned by the player, and I'm okay with them not being the most optimal way of playing the game for reasons like the drawbacks not being worth what you can gain with the extra ProN, but in my opinion that should be because the things you can spend your ProN on at the endgame are not as efficient as just avoiding the drawbacks of failing to meet the best thresholds in earlier events or getting the non-profitables that go away. But not just because there is absolutely nothing left to spend your ProN on in the whole world (sx liquidation notwithstanding), that just sounds silly.
