It's actually harder to string more wires as a new company, because so much is already owned by a few very big players. So you have to buy access to the infrastructure from your competitors before you can even compete with them as an ISP. The opposite is true in the UK where the government owns the Tier 1 network (and possibly Tier 2, I forget). There, startup companies offering competitive services and prices don't have nearly the trouble flourishing as they do in the US. You seem to think that essentially any role the government has in a market economy is going to be negative for consumers overall, and that is patently false.
