I've had this debate many times with friends. Am I hyper efficient with my spend? No, am I happy about my decision making process and/or less decisions to make? Absolutely.
If I see micro transactions for reading articles SMH. Conceptually I see where you are going but it would have really bad ripple effects IMHO.
Going forward, in NYC, I'm just going to use OMNY, since it's not in all stations.
It costs me around 170€ per month, which is way more than I would spend if I bought just a subscription for my city's public transit plus train tickets as needed. But even if I pay a few bucks more, it's totally worth it because it changes how I approach travel. I can wake up in the morning and decide on a whim to do a day trip to a city 200 kilometers away for no extra charge. I can decide on Thursday evening to take Friday off and visit my parents (who live 500 km away from me) for the weekend.
(Side-note: Obviously a lot of this is not possible right now because of the plague, but at some point, all parties involved will be vaccinated and I can resume my travels.)
