> People don't pay that much for occasional usage and many/most people will organise themselves to use all or most of their weekly allowance when the expense is in that ballpark.

I don't think that's accurate for professional users. Personal users, especially those for whom $200/m is a significant cost, will definitely try to get the most out of it.

I know several $200/m user (I'm on the $100 personally), and they've all had the same experience I had when first upgrading to the max package: initially you try to use it as much as you can and feel like you need to keep it busy. But that goes away after a few days and you use it when you have need. The primary point of the max tiers for my peers is to not hit limits during their work if they occasionally use it intensively because it's disrupting to have to wait for X hours to continue.

If you get a benefit from using it, and you bill at $200 an hour, and you work 160+ hours a month, the $200 monthly cost doesn't register as a significant cost and you won't make it determine your usage patterns. I'm sure that'd be different if VC money goes away and it turns out the true price would need to be closer to $5k, but at this point it's similar to your ISP for fiber costing $80 a month. You enjoy the speed for a few days, but then it becomes the new normal.
