Question

Why aren't there any homes in Italy built with aluminum or vinyl siding? No processing plants?

Answer 1

because its cheap and not many people here are going to find it attractive....  here we have our  houses built out of quality stuff, not plastics

Answer 2

For the same reason you can't get a house in the southern US with a poured concrete basement, or a house built with standard sized lumber in Greece - tradesmen are used to doing things a certain way and it's really difficult to get them to do things differently.
