Well, not really. The Witness was priced what it was because it cost a lot of money to make. Given the kind of game it is, pricing it lower would increase the chances of not making his money back, while not really deterring piracy because people who do that will find any kind of justification to do so, which was the entire point of the post he responded to. The price just provides them with an excuse.
The implied solution to come from that train of thought is to just not make games like this since they cost a lot to make and people will pirate it when you ask a reasonable price. The solution is to cave to those extremely price sensitive thieves who probably won't buy the game regardless. Which isn't actually a solution, or particularly insightful.
