I will mention again that fanatical whimsy does not supercede the human lust, in this case for knowledge. You can't honestly say that you wouldn't want to know if the Earth was flat, in all honesty.
As for why people argue for the flat Earth model, that may be a different story entirely, but you ought to figure that one out yourself.
And as for why the government (or at least NASA and the space programs) want to conceal the fact, it's most likely money. NASA gets billions of dollars of tax money for funding space travel, and since they're obviously (in the Flat Earth Model) not using it for space travel, they've got at least a few hundred million per year to spend on nothing except themselves.

I can and will say that I don't want to know. Or rather, don't care to know. Whether or not the world is flat has absolutely no bearing on how I interact with it or its population. It's like the philosophical question of 'if a tree falls in a forest with no one to hear it, does it make a sound?' Any definitive stance maintained on that question is an intellectual vanity, nothing more, since the nature of the question is defined by the tree's lack of effect on the conversationalists.
You can't fob off my questioning as to why people argue for the flat-earth theory as 'something I should discover for myself.' What do you think I'm doing here in this thread? That's right, discovering for myself. Why, if you do so, do you argue for the flat-earth theory? What motivated you to pursue this course of action?
Finally, how can that argument have any validity? The round-earth theory originates in the Renaissance era, which predates the formation of Nasa and the United States by a considerable length of time, what conspirators were lurking in those times, profitting from their deceit? Even the concept of Space Travel was outlandish at the time the concept was embraced, so how does this conspiracy theory work? I honestly don't understand and I truly want to know...
