You could double everything in this post too and that's only 60% consumption.

• 20 m² of personal living space + 20 m² for every 2 ppl as bathroom / kitchen
• 4200 kcal/day
• 2800 kWh/year, but this already includes public services (education/healthcare)
• 1 washing machine per 10 ppl
• 2.4 kg clothing / 6 months
• wear tops for 1.5 days and bottoms for 7.5 days without washing
• 1 laptop per 2 people with a yearly power consumption of 62 kWh. (bizzarely they talk about an 800 MHz computer and seem to confuse HDD and RAM). If your gaming computer used 400 W you could use it for 300 hr/year.

That seems a lot more reasonable to me and we still come in under carrying capacity
