Why should a relatively poor upstate new york taxpayer be paying 50% of the fare of some young finance bro going to work?
Also removing prices removes information. For instance the ferry costs something like $15 per rider to operate compared to around $5 for subway. With both trips at the same price to the consumer, you make the marginal rider indifferent to the two in terms of price where it would be beneficial to have that information to save money and divert resources to the more effective mode
> roads to places I'll never go
Gasoline tax and toll roads are a good way of linking those who benefit to those who provide the good.
> schools my child doesn't attend
A lot of people move out of high tax neighborhoods when their kids graduate high school. I don't think school should be tied to real-estate anyway because it creates really perverse dynamics (people without money end up going to the worse funded schools). So that model doesn't exactly work well right now
> medical procedures that I don't need
I buy health insurance voluntarily and gladly pay for medical procedures that I don't need on the off chance that I need an expensive medical procedure in the future
Or to look at it another way: assume some genie offered to dismantle the NYC train/subway system for free. Assume you're the government and only care about maximizing revenue. Would that be a good deal? Of course not, even if the system wasn't self-sustaining from fares.
