Your Gnucash usage question leads me to an accounting question. And I am 
not an accountant, so my ignorance is likely vast. However…

Why should the accounts which track the physical assets be Equity 
accounts?  Why not make them Asset accounts?

And then, David Cousens points out that what you need to track physical 
assets is an inventory application, and GnuCash is not an inventory 
application. How does that inform your use of GnuCash?
