Some ideas:
1. The owner of the 80k bitcoins is Satoshi himself.
2. The owner lost the private keys years ago, and just recently found them.
It is not Satoshi, he is gone and it is time to make peace with that. Even if they were satoshi's coins, it is not going to be him.
3. Is it just a coincidence the 8,000 bitcoins lost in the landfill by the owner James Howell is similar
to the number 80,000? Of course its ten times less than 80K but the numbers are similar,
but off by just one zero.
Just a coincidence yes.
