Man, did you ever read other post before posting your own? Above, o_e_l_e_o gave a great explanation on why not:
For 1 satoshi to equal 1 dollar, the total market cap of Bitcoin alone (never mind the rest of the market) would be 2,100 trillion dollars, which is more than 20x the GDP of the entire world. The only way it could ever happen is with collapse of the US and hyperinflation of the dollar.
