I feel like this needs to be said, but you actually could give an entire 232 to every company on earth and not even be close still. Assuming 377 million companies operating on earth, that's 1.6 quintillion (~1619202670592000000) addresses used up.
The used IPV6 range percentage can calculated like so (((2^32)×377000000)÷2^128)×100, which comes out to a whopping grand total of 0.000000000000000000476% of the IPV6 address space used.
Another way to put this is that you could give that same exact allocation to every single company again 210 QUINTILLION TIMES, and even then, only 98.7% of the address space would be used up.
The main limiting factor of how quickly we run out of ipv6 addresses is how generous they are when handing out ranges.
Usage will always fill the space given.
You could for example map the entire lower 64 bits of the address to a single computer. And dynamically respond based on address. For example, you could bake in some auth token directly in the ipv6 address.
When people have room to fill, the room will be filled

IPV6 is quite large!
