The only way to enable jetstream for an account is by setting one (or more) limit(s) of the jetstream settings for that account

[anthonyjacques20]

What version were you using?

Using nats-server 2.10.7 and version 2.8.5 of nsc

What environment was the server running in?

Mac Apple M1 Pro

Is this defect reproducible?

# Create operator
nsc add operator --name local
# Add account
nsc add account APP
# Describe account
nsc describe account APP

This shows:

With the main note that Jetstream is Disabled

# Set an arbitrary limit for jetstream
nsc edit account APP --js-mem-storage 10g

We now see Jetstream is enabled:

| Jetstream | Enabled |
| Max Disk Storage | Disabled |
| Max Mem Storage | 10 GB |
| Max Streams | Unlimited |
| Max Consumer | Unlimited |
| Max Ack Pending | Consumer Setting |
| Max Ack Pending | Unlimited |
| Max Bytes | optional (Stream setting) |
| Max Memory Stream | Unlimited |
| Max Disk Stream | Unlimited |

# Remove that limit
nsc edit account APP --js-mem-storage -1

And now Jetstream is still enabled:

| Jetstream | Enabled |
| Max Disk Storage | Disabled |
| Max Mem Storage | Unlimited |
| Max Streams | Unlimited |
| Max Consumer | Unlimited |
| Max Ack Pending | Consumer Setting |
| Max Ack Pending | Unlimited |
| Max Bytes | optional (Stream setting) |
| Max Memory Stream | Unlimited |
| Max Disk Stream | Unlimited |

Given the capability you are leveraging, describe your expectation?

My expectations is that there is an Enable Jetstream option for an account that doesn't require setting a Jetstream limit.

There is a --js-disable option, would be great to have a --js-enable option that enables Jetstream for an account without requiring any limit manipulation

Given the expectation, what is the defect you are observing?

A --js-enable option (or similar) appears to be missing.
The static auth option allows for a jetstream: enabled option for comparison
