Frankly, this "basic income" is so bad, this would be a socialist strawman if it wasn't real and having folk actually shield the concept.
people that focus more on social value would have more availability to dedicate themselves fully to it
people would only want to work on something they truly enjoy doing, increasing quality of services
Do it on your own time. That's not other folk's job to fund your pig eating contests or something. It'd be nice if you could just do whatever you wanted everyday without having to work in your life, but that's just not happening.
What the government must do is shield your life, and in Switzerland, there's been a welfare fund for a very long time, doing more than enough already for folk to "focus on social value" or whatever.
businesses would require smaller net profit to remain in business, providing goods and services at lower costs with higher quality
The difference would not be significant for successful businesses. If the business is so small that it makes less than 8 400 $ each year, it doesn't need to work, and will be sold, in order for folk to do their "social values". If it makes significantly (worth it to keep it) more, 8 400 $ will be a drop in a pond, and furthermore, no grounds that prices would be lowered and quality would be highered - if anything, production would be lowered. Folk still want to make a profit, and they're not going to lower it even if they think they don't need the money. And there's absolutely no grounds that the quality would be highered, either.
there would be a significant drop in state expenses incurred with processing social welfare
You can't bring up an argument of expenses, here...this would just replace the old welfare.
stress and depression caused by unemployment situations would disapear
Switzerland has had a more-than-enough welfare for not doing anything already for something 30 years. Noone should ever have to fear going hungry, but that wasn't/isn't happening.
