Monero is just a digital currency anyway, similar to Bitcoin if Bitcoin had cheap transactions. You can hardly run anything on the network. Something like Ethereum might be an option once it scales properly and when transaction costs come down. I do agree there needs to be a financial incentive to run nodes. A blockchain which does not discriminate in terms of applications running on it could be very valuable in the future. Privacy is important, not just from a civil rights point of view but for businesses too. There's a reason corporations care about IT security and encryption.
