Once again with this argument.
It's one thing to dismiss poker played with play money/chips from your point of view as a waste of time for you personally. It's another to define the entire idea as a waste of time period, and therefore flawed or misguided.
Hundreds of millions have hobbies which they take seriously with no relation to money, the list is endless. Many are dangerous (diving, rock climbing), many involve highly developed skills. People take them seriously.
Hundreds of thousands play on line with play money day in and out, certain sites have leagues and the competition is fierce. As noted recently, Terrance Chan even said on DAT poker podcast that anyone who has built a play chip stack of tens of millions of chips is playing seriously (and he used to be somewhat dismissive himself).
As for people buying play chips, there is a valid reason- that of being able to play at the highest levels against stiffer competition with high buy ins. In the elite games you sometimes see players in billion chip pots (and that is serious because they can be wiping out rivals entire bankrolls which have taken a considerable time to amass).
Further, regarding the tone taken to play money - people making such comments seldom consider or acknowledge for many, play money on-line is the only learning tool they have at their disposal. Many people do not have any card/poker culture in their family. Many live in countries where live poker/
casinos are either banned or simply do not exist. If interested to play poker, the only avenue they are provided is to learn on-line with play chips.
Many graduate through this to freerolls and then cash. But others opt to stick with play money because their lives are rich and complicated as it is ( I know of doctors, lawyers and scientists who love the game...but only indulge on play sites. They do not need further stress in their lives).
So yes, for you personally, play money might be of no interest whatsoever. However that does not mean it is not an invaluable learning tool and of deep interest and played in a competitive environment for others.
