Quite often someone puts something together, leaks a bit and they blame ****** seals.

I take your point, and decent prep is always a good idea. But your particular example isn't great. Even if there are confirmed no leaks before the track day, even a low-speed crash on track can break something that then leaks. It can take a very long time to safely clean up coolant from a track surface, while water can be cleaned up in minutes. People who run coolant on a track and cause issues for other people if/when they crash and the track is unusable for an extended period are just being selfish. Not to mention that at track speeds and temperatures - the coolant isn't actually any better than water + a little water wetter or similar additive at moderating the engine heat, in fact it can be worse.
