Can someone come up with a well reasoned argument not to prepare?

I've been prepping for years because I made it through a crippling disease and saw I had no food in my home. Reuters has a very snide and patronizing article about preppers and threw in a little pop Psychology as well. So all trolls and .gov workers can you give me a good reason not to have 6 months of cash and 6 months of everyday goods on hand. Remember FEMA recommends at least 3-14 days at a min. for all goods. But I'm just a high school dropout and trying to learn. /sarc So tell me all great and powerfully smart folks how prepping is a bad thing?
