Name-dropping?  This is just Intro to Philosophy stuff.

They are both part of the language game of creating/discussing fictional
texts.

Well, a stock option is a socio-cultural artifact.  It's an agreement by one
party, a publicly owned corporation, to sell a set number of shares to
another party, usually an employee of the corporation.

Well, by that measure, SUMO is a success.  There are dozens of organizations
that are actively using SUMO.  Just google SUMO ontology or ontologies.

I don't think this is the issue.  I would tend to regard any extra
metaphysical assumptions beyond naturalism as just so much hot air.
However, see below for my response to your specific examples.

In the SUMO, change is always represented as a 'Process' from one
'Attribute' or 'Relation' to another.  For example, 'Melting'
(http://ontology.teknowledge.com:8080/rsigma/SKB.jsp?req=SC&name=Melting&skb
=SUMO) is a change of state from 'Solid' to 'Liquid', and 'Translocation'
(http://ontology.teknowledge.com:8080/rsigma/SKB.jsp?req=SC&name=Translocati
on&skb=SUMO) is a change from one location to another.

In the SUMO, to be an instance of 'Process' or 'Object' is to have a
location in space/time.

I don't see that the ontology has to take a stand on what pressures,
temperatures, and other physical quantities *really* are.  All we need to do
is to offer a formalization which allows different people and different
systems to say all they need to say to communicate with one another and
perform certain standard inferences.

I think I'm still a naturalist simpliciter.
