That's a tricky position in the UK: We're in a severe recession; no-one wants roads dug up; the last time we had a fibre glut it didn't end well for pretty much anyone involved.
Speed of connection isn't what's preventing most people from working from home - stupid PHBs do that.
Synchronous 1Gbps is unrealistic for the next 5 years. Maybe asynchronous 100 Mbps is possible. Not forgetting that the aim is for everyone - isolated villages in Wales and Scotland - not just the 4 big cities who can afford it and need it.
I'd agree that if people are putting fibre in (or building new housing (as someone else mentions)) or even just digging up the road that there should be a requirement to install extra fibre. the stuff itself isn't that expensive and putting lots in gives you economies of scale.
I'm just more realistic about finding the money to pay people to light it.
