I wonder if a lower cost service like VPNs could reasonably create an “endowed” account: basically pay enough up front that when invested, the returns on the up front cost are about the same as the monthly cost. If you’d need to make €60/yr, you could probably achieve this with a one-time €1,500 payment. Does it make sense for anyone to pay that much up front? Maybe not. But for people that REALLY want to see the business model succeed and/or are way too wealthy considering their mental laziness, adding an option to pay a totally absurd amount once and then forget about it might be useful, even if that payment is way higher than any normal person would pay.
