It takes more than that. We need political maturity and stability. There is no way we can send people today on a 200 years journey and be sure they will both make it and be able to create a somewhat stable society on the other side.
Also, that would be a earth level effort, another thing that is seriously irrealistic right now. The very best we can achieve right now is the ISS and that's pathetic even compared to current tech.
The biggest push in recent years has been around privatisation of space exploration. It is going to take decades, probably centuries before a commercial model of space settles down and non-profit utopist project like that would be conceivable.
