This is a straw-man argument. Nobody would ever (I hope) try to implement UBI that way. It would be a disaster.
But this is a general problem. Proponents and opponents of any thing, are usually talking about very different versions of the thing. If not, they have incompatible perspectives on the thing. I can explain more about this if you like - you really need to see examples to see why it’s important.
There aren’t really serious doubts about whether UBI would work, or what its effects are on society. But there are many misunderstandings about what UBI is.
If working with live wires, do the whole thing standing on a wooden stool. You must have a thick insulator between you and ground. You will probably touch a live wire at some point, and the size of shock you get depends on how well insulated you are from the ground, walls, and other objects around you.
Don’t bother wrapping wires around you.
If you connect the live to the earth wire, you will blow the fuse, and probably destroy the wires too. Then you’ll have to rip out the plaster to lay new wires.
This is not difficult if you are careful, not tired, and have good common sense.
Wrap the live in electrical tape first. Only unwrap it for the few seconds where you are putting it into its connector. That’s the only step you need to do carefully.
