If I spend $15 on drinks then Ubering to and from has just at least tripled my cost of going out.

If going out with friends costs $20 a head instead of $45, more people will want to do it.

Even with trains, commute isn't free.

Yes, you can see I costed out a non-car round trip at $5. In NYC on the MTA it would be $5.50; in DC, between $4 and $8.

One thing I do in DC is ride bikeshare to the bar (where the amortized cost of the ride, with my annual membership, is basically $0) and then take metro back ($2).

And of course this is all moot if you can just walk, since it is always free, which is one major benefit of denser mixed use walkable neighborhoods.
