No sharp line, but hardly artificial.

If someone gives you a cake, and I take the whole cake it's clearly confiscation no? You got no cake at the end.

If someone gives you a cake and I take a slice (say 25%), then it is clearly not confiscation, since you got cake correct? Not only that, you got most of it.

Depending on who you are and why you took my cake, it could be a tax, confiscation, theft, a fine...
