It is true that it can be copied again if only one nodes survives.
But one node cannot digest the whole network, so it then would be offline for some time until other nodes come online again.
Depending on the offline time, after that time there maybe won't be any old users interest to copy anymore. Especially if they already have local backups of their texts, blogs
I will take a look.
Please do take a look, and let me know. Guten nacht
