Ah, well, self-schooling is always a good position from which to make
sweeping generalisations.

Because the whole point of a database is to be a coherent set of
connected facts. What is your opinion on handling:
1. Differing character-sets in different databases
2. Differing locales+sorting in different databases
3. Cross-database foreign-keys and other constraints
4. Differing objects with the same names in different databases
5. Handling #1-4 when the databases are on different physical servers.

It sounds to me like you want to share a single database between users,
possibly using a suitable mix of schemas and roles to apply suitable
permissions. If you don't want them to have shared access to the data
then you can have separate databases and grant them access only to their
own DB.

Nobody is forcing you to. You'll have problems with procedural
languages, custom types, dictionaries, replication, GIS though.
