You're just repeating the last part of what I wrote -- that the taxes would be low when amortized over a large number of items -- but ignoring the rest. The point is, New York does this all the time: yesterday a surcharge on food delivery, today a "congestion tax", tomorrow a "global warming fee" on electricity consumption, a "save the whales" fee on straws, or whatever else. The number of sneaky fees and surcharges and social-engineering taxes in NYC is enough to make even the most ardent liberal begin to resist. Eventually, you're paying $25 for a hamburger and wondering why you can't find staff for your store.
Look, I have no problem with taxes. Just be honest. Don't sneak them in and lie about them and pretend that they're punishment for New Jersey car commuters when most of the revenue will come from the people who live here, directly or indirectly. If the people want to vote in another billion-dollar sales tax for the MTA, great. Go for it.
