Disruption to traffic? And roofs don't have to be maintained when no PV is installed, no satellite dishes and antennae are put up, nor new roof windows?... Come on, this is hyperbole too much.

The projected cost of the solar feed in tariff in germany

...is something established producers (who stand to lose market share) like to play around with. In particular, they like to forget about subtracting market prices.

if the same money were allocated to nuclear build, the result would be a fully carbon free grid

Because nuclear can replace intermediate power and peaker plants... not.

the same amount of money spent on "more wind and pumped storage" would also result in vastly more CO2 displacement per Euro spent

The economic point of a feed-in law is not to subsidize the cheapest and most CO2-friendly generation. It is to create a large enough separate market for competing producers of new, still expensive technologies to bring prices down by reailising economies of scale and doing research with a significant budget. Which is exactly what's happening.

Anything and everything is, and will remain, cheaper than rooftop solar

I wouldn't be so sure. Prices are coming down -- and so are feed-in tariffs due to degression. (Even if the current government leaves the current degression rate alone, the rate for 2015 installments will be half of the 2008 rate.) The industry even claims that the open market price level could be reached by 2013, which I doubt strongly, but still inmature technologies like HDR geothermal or wave power should be overtaken by then.
