Weisenthal said that Bitcoin is intrinsically worth nada, and responds to those Bitcoin supporters that say USD by the same definition is worth nada, but Weisenthal then claims that USD is intrinsically worth something because the US government says it is worth something.

Now this is wrong in two aspects:

1) USD is worth something not because the US gov says so, but because China says so. The day China says that USD isn't worth anything, the USD will collapse.

2) What would happen if China says Bitcoin is the new world reserve currency? At that day Bitcoin will have intrinsic value by his own definition. So the only thing we can conclude is that he thinks that this can never happen.

But it can! China has on multiple occassions wanted to dethrone the USD as world reserve currency and replace it with EDR (Extended Drawing Rights). However, I think that the day will come when China realizes that Bitcoin is a much better solution than EDR. And when that happens, Bitcoin will have a market cap of 10 trillion USD at least which would imply around $1000000 per Bitcoin.
