Actually, I like the Steem basic income better than the traditional basic income idea. With the steem basic income, you at least have to post in order to receive it, which makes at least a small contribution to the community.
That alleviates one of my typical issues with the basic/universal income idea. Let's just say I tend to be a capitalist, the more value you provide to people the more you receive. I don't necessarily deserve anything that I have not provided value to someone to earn.
I think it's just human nature for us to associate work with value. This post would be an example. Provide value for a reward, upvote and some comments, are exchanged for the SBI or exposure to a wider audience increasing future potential. Otherwise you would just give it away without the upvote or comment.
