If you have an owner who is absent, who just goes away and leaves a property to fall into rack and ruin, it is better that somebody put that property to productive use.

How about my bank account, that I have left for, say, 10 years?
Can someone claim they can put it to better productive use, and take it?
After a certain amount of time, banks do exactly that. That caused a lot of problems with descendants of Jews murdered in the Holocaust if you remember. If the bank doesn’t claim it, then the government does. Look up “escheatment”.
