In any other town, I would agree with this premise. The city should easily be able to afford the infrastructure expenditure.

In Portland, however, it isn't going to happen. The equity proponents will turn out and demand that a) a new tax will be required to fund it b) only a fraction of the population should pay that tax c) only a fraction of the population should have to pay for the service once it's installed.

The desire to turn every program into a handout would kill this before it ever started.
