"Well the laws of Australia prevail in Australia, I can assure you of that. The laws of mathematics are very commendable, but the only law that applies in Australia is the law of Australia."

Attempting to ignore physics and mathematics when making the law tends to not work out well....

At the same time a law can't narrowly target a specific technology, which then is bypassed easily by changing some technicality, but must be broad enough to cover different technical implications, while specific enough to catch the case you want to catch.

If a company wants to do business abroad they'll have to conform to those laws.
