It seems you have problems understanding what value is. Value is that benefit described in the OP.
Don't assert something as fact that has been disputed and discussed by economists for literally hundreds of years at this point

That definition of value is
your definition of value. And while it's a definition that might be shared by many people, it's not
the definition of value and it's not even necessarily
a useful definition of value.
With cryptocurrencies however, no resource exists that can provide benefit to cryptocurrency owners. So there's no value that you can determine or talk about. Only a log exists that crypo owners can update via wallet applications. And that log can be downloaded for free by anyone.
Within your framework, the value of cryptocurrencies comes from enabling frictionless monetary transactions. Short of that, the majority of stocks in the finance sector would be, by your definition, not assets either.
You go round in circles. There are no monetary transactions. Transactions are done with assets. In crypto, a log is updated - which manifests in changes of numbers associated with addresses. It is mind blowing how you crypto people talk about some magical asset but you see with your own eyes that it doesn't exist.
