How can you validate a logical argument with a 'not always'? AND
without 'clarifying' your argument!
Following _that_ logic, you are incorrect. Examples of free (as in NO
connection costs, the basis of my argument) databases: PostgreSQL,
Derby, HSQLDB, etc, etc.
'My' time in creating the database is not free. And regardless of the
solution, Commercial or Open Source, there needs to be someone to
maintain it, whether that is via vendor support or inhouse techie. So
neither are free in the sense that time is money: Either paying for
support or being employed to do so.

None of the above: It needs to be flexible enough to scale in
connections without incurring a cost penalty (see named databases
that offer this above).

Again, it is a question of scale and simultaneous connections.

There are global companies with more than that number, regardless of
how few per 'office'.

Where does it say that?

That is your point of view. I expressed my opinion towards connection
costs. Why are special agreements necessary when it could be easily
resolved without concessions? Why would there be a need to change
your model on the basis of a conversation?
