A couple of main airports are indeed well connected to the public transit network (for example Amsterdam Schiphol has a train station under the airport connected to the main train line and it takes about 15 minutes to get to Amsterdam Centraal Station on a regular commuter train).
However I was talking about the peripheral airports, which are at best on a train line which doesn’t have many options (such as London Gatwick) or at far end of a subway line as peripheral airports are the ones that could potentially be faster to use for somebody living outside a main city (which, as I mentioned above, in my own experience was not the case).
Fair. It depends on the city too many do have transit to the Airport or are working on expanding out that way.
