Ridiculous thread and link. He doesn't say that.
He says water has a cost, like other foodstuffs, and should have a price which reflects that. So, there are obvious costs to do with water, which are reflected in our water bills... which he says should be the case. He then also says that those who can't afford to pay should be sorted out/still have access to water.
Paraphrasing from the relevant part of the video,
'Water is the most important raw material. And the question's whether they should privatise. On one hand there's NGOs saying it's a public right for free access to water. Then on the other hand it should be considered like all foodstuffs, and we should recognise it has value (with people paying the market price for it). But then we should take specific measures for the part of the population which has no access to water'
I don't see anything shocking in what he said. It's completely fair.
