ROMs. Why not?

There is one question that has forever tormented gamers: To emulate or not to emulate.
For you n00bs, emulating is using your computer to play downloadable games released on earlier consoles such as PS and N64. Some people call it immoral to emulate, however, I see it as a perfectly right means of playing the classics. Firstly, most of these games cannot be purchased anymore, so there is no profit to be lost. Second, those games that can be gotten off Wii Shop Channel and XBox Live Arcade are far too expensive considering their age.
Why should we be forced to buy PS2 to play Final Fantasy VII?
Just something to think about.
BTW...
I just got AVP2 and Jumper. =)
