The point of serverless is that I'm buying transactions, NOT a server.   It
could be a MQTT transaction, or a web page delivery, or a DNS response or
storage in a Database, or whatever.

Let me see if I can use a different item to describe why I think the term
serverless is fine:

If you were to state that buying power from the electric grid is
"generatorless" I wouldn't have a problem with that.   Technically there
are generators in the power grid, but I don't need to know about them.   As
far as I'm concerned the power arrives at my place of consumption over
wires and I sure don't have to know or care that there are generators at
the other end.  So from my perspective, the electricity I get from the grid
is 'generatorless', meaning I don't have any generators, I don't have to
manage any virtual generators, and I don't really care if there are
generators at the other end as long as I get power.  But yes, technically
it's not 'generatorless' power but again, it could be solar panels and
batteries or a zero point energy source for all I care.

So "serverless" more has to do with what is visible to the consumer of the
service.   I don't know how the service is put together, I don't need to
know if there are any servers at all.   Maybe they've implemented the MQTT
broker in a pile of FPGA's, are those servers?  Regardless of how the
service is architected (whether it has a server on the other end or not), I
don't care, as long as the service I'm paying for is delivered.

In a traditional 'server' architecture, I'm going to spin up a MQTT broker
server, and a database server, and a web server, and probably a few other
servers to do housekeeping work, and pay for all of them to be available
24x7 or as needed.   With serverless, from my perspective I have no
servers.  Yes, these pieces probably exist in some form, but someone else
does that and I don't care if there are zero or a million servers as long
as my workload gets done.

So serverless really means that I don't need to have any servers that I
really know about, virtual or otherwise.   Someone else might, but I'm able
to put together an entire product without knowing or caring if they do or
do not exist as long as the function is completed.
