IMO it's a good point lol. On at least two levels.
Putting aside the adventurism, we should encourage those disillusioned by electoralism to still remain engaged in non-electoral work, particularly if it is something they are interested in (obviously discouraging adventurism).
There are a lot of Western lefties that cannot imagine a productive program outside of adventurism. They're detached from the slow, difficult work of long-term organizing and agitation. This can be politically paralyzing because they don't actually want to bomb the Walmart, and they don't want to do electoralism, so they do nothing instead.
