It’s also completely fine under all international law.
Following copyright law is more like a trade agreement, so if you feel wronged enough as a nation it’s completely uncontroversial to suspend all or all international copyright law and deal with the consequences (mainly the us being very salty about it).
The EU contingency for a US attack on Greenland for example is among other steps to suspend all US copyrights recognition and starve the US service industry.
I interpret this as the “boundary” being one-way away from us, with us at the “top of the potential well”. As opposed to the more commonly proposed idea that the universe is inside a black hole.
Hawking radiation is based on the curvature of the event horizon, so in this case I think it should balance negatively, sucking out energy from the universe, probably by releasing negative energy particles in the particle perspective.
This doesn’t make physical sense, which matches that such an event horizon shape also doesn’t make sense and shouldn’t be able to be created I think.
