Yes, current crisis. Everyone agrees on the fact that the virus will probably spread and become much more widespread. Isn't it logical that costs will go up too, especially if the state decides that the economy isn't worth the loss of lives? Is slippery slope just saying that cause and effect exist now?

I don't see how the original comment was unreasonable in asking what is the threshold where economic losses are too high. Halting all economic activity to completely stop the spread of the disease and prevent deaths amounts to a 100% taxation since you are forced to not work and generate revenue. Whether that is acceptable or not isn't my point, but asking the question isn't a fallacy

There are no economic losses too high as long as loss of life is less.

They didn't mention confiscation anywhere.
