It's not "prohibitively" expensive. It's expensive. Besides, it's not just the $10k, it's the $150/h every time you want to take the plane. That adds up quickly.
So a PPL is useless unless you're willing to spend $2k+ per year to maintain it. Do you need to go somewhere far away, often enough for that to be worth it?
Your rebuttal again is how expensive it is to fly. Some would almost say, prohibitively high?
