2) Ultimately it is not income that is needed to survive but resources properly organized. The cost of survival is getting cheaper and cheaper at an exponential rate. You wouldn't know that though because they keep raising the bar on what it means to "survive"—big screen tv, air conditioning, car, etc. The amount of work required to live according to living standards 100 years ago is rather minimal.
3) Where does this "basic income" come from? If you are taking it from others who produce value then how are you any better than a slave owner? The only difference is that instead of owning and taking the livelihood of an individual you are taking it from everyone collectively in smaller amounts. The moral principle is the same.
4) Why would people work if they can just take from others? Everyone will do the least amount possible because everyone else is just going to take their profits so why bother. Communism didn't work so why are you proposing it now?
5) You can't protect people from being stupid. Unless you are physically handicapped or retarded, in which case there is charity and family, it's really pathetically easy to survive in today's world. You aren't being chased by tigers. Agricultural yields are 100x than they were just a short time ago. The Internet provides a vast amount of resources to better yourself. There are greater abundances than ever before and people are generally charitable towards others. If you can't survive under those conditions there is something wrong with you.
6) I find it offensive and an attack on my personal liberty that you would demand that I sacrifice my livelihood so that another doesn't have to work hard and make wise decisions.
