We have and have had societies in the past where everyone got equal compensation. Do you think those societies allowed loafers to goof off all day and contribute nothing?
That's not better. If someone wants to be lazy, put in the minimum effort, and spend the rest of their time playing games that's their choice and they shouldn't be punished for it by forcing them to contribute to society to "earn" what they've been forced to receive. That cure is far, far worse than the disease.
I'm just saying loafers isn't a deal breaker. Past societies dealt with it by not allowing it. If we ever realize a future utopia we could probably live with a small percentage of the population spending their whole life doing nothing but gaming. But it is my strong (completely unprovable without actually trying it) suspicion that many people who game their lives away actually would rather be doing something else (e.g. working in a space station), they just don't feel they have the option.
