There's also business use cases to think of. I've often had to spend what on a personal level would be an obsene amount of money but in a work context was justified. Most common examples for me have been very long taxi journeys, last minute and therefore way overpriced flights, and same day international shipments. I've never needed a helicopter, but for example if there had been some screw-up that meant I badly needed to get an unreleased product to a press event in the next few hours then sure I'd have spent a few thousand on a helicopter rather than waste the hundred thousand spent on the event. (Side note: sounds like a "should've been better prepared" situation, but I've seen this happen with so many companies in the tech industry. Normally solvable by expensive taxis or couriers rather than helicopters, though.)
