Thanks Dan.  Perhaps my use case may shed some more light.

Distributed ledger technology is a hot topic right now, and I was thinking
that a "has" predicate could be used to create a distributed ledger.

<Alice> has 10^^<#satoshis>
<Bob> has 20^^<#satoshis>

Indeed it would be possible to create a payment using a PATCH in this way,
creating a truly scalable distributed / decentralized ledger.


Perhaps 'owns' is a better term here, tho im not sure

Question 1 is:

<Alice> has 10^^<#satoshis>

the same as

<Alice> <#satoshis> 10 # probably not as 10 would be xsd:int

Question 2 is:

<Alice> has 10^^<#satoshis>, 20^^<#satoshis>

legal?

You want to avoid having multiple balances you see.  And if its possible to
avoid without SHACL / ShEx that would be a simplification.
