In order to achieve the savings you imply, then z/VM must move to the z/OS 
model in which, except for a few specific functions, an ESM is required 
for proper operation.  NO native CP security controls beyone those 
required to restore ESM control vis a vis SYS1.UADS in order to login to 
TSO.  Any function dependent on the ESM will be configured to DENY access 
without the ESM.

You would HAVE to buy an ESM, whether from IBM or CA.

And THAT will be acceptable only when folks wrap their heads around the 
fact that z/VM systems WITHOUT an ESM will fail a modern security audit.  
The primary example is the presence of unencrypted passwords in USER 
DIRECT.
