We've a long history of trying to make a coin fixed to a value of something but miserably failed.
No two things can have a same value as the value is always decided by the market with supply and demand.
What if someone launched another USD token with an infinite supply?
I mean it would take longer to launch another USD token as everyone would be skeptical, but....
This is a huge market opportunity to take advantage of, so if you do it right, you can definitely go somewhere with it.
