You want to be able to answer "how much does Bob store", which can only
be answered by a unitary authority for the relatively small group to
which Bob belongs.
If the system is truly decentralized, one cannot answer the question
"how much does Bob store". One can only answer "How much does bob store
with me?"
If the system is truly decentralized, if it is peer to peer, there are
no separate storage grids, just sea of peers. Files are stored on the
peers with which one's software has generated relationships, not on the
system with which the human has opened an account.
In one of the proposed accounting systems, each storage server accepts
storage authority from a single account server, or a small number of
account servers. Thus each account server represents a single tahoe
storage grid, a single place where one may put files, a single thing
that is rather like a single file system.
With the proposed accounting systems, difficulties will ensue should one
wish to spread a file in k of m shares across n such systems, in part
because one has the right to store data because of a relationship with
the human authority in charge of an account server. To store data
across n such systems, even if the software allowed it, and I don't
immediately see how it could, it would be necessary to manage n sets of
human relationships, which is prohibitive.
