Fuses are a safety mechanism to protect against an overcurrent situation heating up wiring and potentially starting a fire.
The purpose of a fuse is not to blow, but to only blow when dangerous amounts of current flow through the wire they are protecting.
eFuses are a hackish way that System on a Chip makers have created to try and permit patching flawed hardware with questionable firmware. Permanently breaking electrical contact of a circuit in a chip is definitely damaging that circuit.

The purpose of these fuses is to blow and serve as write-once storage memory.

No, eFuses are literally the only mutable nonvolatile storage that can be implemented inside SoCs in modern silicon processes, because you can't put Flash/EEPROM in them for technical reasons. That is why they are universally used for irreversible configuration actions on every single modern high-performance SoC. You will only find Flash memory in small microcontrollers.
The specific purpose of the fuse doesn’t matter. The permanence doesn’t matter.
The fact that the fuse has a function, means that it isn’t “destruction of property”. They added it for DRM, and there’s no evidence to show that it’s anything other than DRM. For it to be “destruction of property”, you’d need to prove that they didn’t do it for DRM, but because they wanted to hurt users. (whether or not it does hurt users is irrelevant for determining mens rea)
Don’t get me wrong, I’m not defending Nintendo; I’m just saying that this is not a criminal matter.

Fuses are simply electrical components. They have no more inherent purpose than a capacitor, resistor, or diode. These fuses are working just as intended, even though its in a use case that you're not familiar with.
