Forks aren't as simple as you might think - who gets to determine what the "original chain" is in the event of a fork? Suppose that ETH forked and one version changed some consensus rules to increase the supply of currency, and Vitalik, the Ethereum Foundation, all of the miners/stakers, and users moved to that chain - wouldn't that be ETH? But it would violate the principle of fixed digital scarcity.

Confiscation of assets is obviously possible via forks as well, but the fact that someone can't take your money without your private key doesn't relate to scarcity.
