The ROM analogy is ridiculous. There's no comparison at the ROM with what's going on at the CN Tower, as there is no chance that the crystal is going away: it would costs a couple hundred million dollars to remove it, minimum. Anyone who thinks otherwise is clueless. The CN Tower's window replacements are relatively easy in comparison.
Meanwhile, the ability of people to achieve change has never been greater. Concerted efforts are required, but an argument that hits home for enough people will eventually win the day.
