Lets take JesusCoin for example.
This coin has a desired name but will probably die in few days and be forgotten in one week.
Now lets say, some big church make a new coin named exactly the same somewhere in the future,
The new coin get very popular and everybody now this coin as JesusCoin.
In this case, the old blockchain will just become a useless and worthless ?
So the community is the one who decide who called what? because if not I quite understand why a new coin is created every hour, its like a name reservation.
Please explain
