No, they would still have missed out on those 104k - but they would have saved 150M. That's .... yeah. A lot of school lunch meals.

No.

That's not "all fares added up to 104 thousand", that's "the fares of people jumping turnstiles and walking in emergency exits added up to 104 thousand".

Keeping the status quo of not replacing turnstiles would have been cheaper. But making fares free would be more expensive.

The largest share of MTA revenue — $7.222 billion — comes from dedicated taxes and subsidies the Authority receives from the cities and states that we serve. Another $6.870 billion comes from fares and tolls. Federal COVID-related aid, which the MTA received in 2020 and 2021, adds up to $2.877 billion.

Which isn't to say that it wouldn't be worth it. Public transit is hugely valuable due to the economies of agglomeration it enables and the infrastructure you don't have to build because of it. It benefits drivers, retail businesses, employers, etc.

An R160 subway car can hold 240 people; they run in 4 or 5 car sets. The E train has 15 trains per hour during peak times, and runs 10 car trains. So that's a capacity of ~36k people, and it shares tracks with some other lines at various points

A highway lane can support 2.2 k people per hour in free flowing traffic. That single subway line can move as many people as a 16 lane highway, assuming that there's no bottlenecks at the exits. Plus the cost of all the parking garages for 36k cars.
