(1) 100 billion over 7 million people is 15k over say twenty years for roughly 750 dollars per year. If the outcome was effective, that sounds like a worthwhile investment. (2) We definitely need increased housing, but that will only make the traffic problem worse. Can you imagine Tokyo or Paris (cities that have built density) without public transit? (3) there will always be something new on the horizon - if you always wait for what is next (I.e. hyper loop) you will never improve infrastructure. Unless you think that hyperloop is the absolute end of public transit? (4) I agree with your skepticism that our governments will spend the money wisely. Since this appears to be some sort of community effort, maybe they will find a way to turn it over to the free market.
