"I'd go out with my friends every night"
Enough to live, not to go out. That's the point. If we're talking, say, $800 per month, which could probably even be double without a big change since that's more of a preference, everybody can live an ok life and there's enough incentive to work. It's also probably cheaper than all the policies already in place, so in a sense the government's grip would be less than now; they control less of the money flow.
The workforce needed will remain, and if not, the salaries will increase until the workforce is big enough.
All you do is keep everyone alive in a cheap way compared to what we have these days.
"try to write the probably awful novel I've been kicking around in my head for years."
If you are ok living with little money, sure. That's the point. You can get wealthy or do something else with your life. You are free.
I'm not saying there are no loopholes, but it could definitely be done. It doesn't make a communistic government any more than what we have now, there's just a social thing in place to keep people alive and from prostitution and what not to stay alive.
Just talking about the income-part.
