The same way we always have. What do either of these issues have to do with BI?
I do not know what you mean and what "always have" means in your context. The article asks to get more money from corporations which I do not think is feasible. I am in the UK now and this country decided to go for universal income we would have to either close the borders or convince at least the whole of EU to do the same at the same time. Please expand your comment if you can.
That's something of an issue of the EU being a union that is very much like a traditional state, limiting -- by design -- the ability of the subordinate elements to effectively manage certain kinds of policy on their own. That's not an issue with BI, that's an issue with the UK as the unit of analysis in considering BI.
You'd have the same problem considering BI in California, for instance.
