Play Money

I recently googled (the most thing I do on the web) play money to see what would come up and I found that there are many people who have read this book and tried it. But to be dissapointed, they all stated something negative about it. Some stated how taxes killed them from their profits, some online pirates stealing their online items, and paypal not helping with the online payments or transfer of funds from one user to the next. So this just makes me question, since it is "play money" should we not look at it as 'real money"?
