Do keep in mind that I never had took an in-depth look at the project and all it involves. Generally speaking though I am strongly in favour of more railway infrastructure, and I find it funny that lots of people (at least in Italy) love to complain about projects such as new high speed rails but they very rarely complain about new highways for cars.
Also the entire point of high speed is to make it more convenient, for passengers as well as trade trains, which possibly might have beneficial side effects not immediately visible. (Using the same logic as you, I could argue: why should we build highways? Surely a 2 lane road is fine!)
Oh and to answer to your question, I wouldn’t mind living close to a railway track, as long as the isolation of the building is decent enough ;)
At least until Darminin comments on Italy’s politics again :D
