Although a very curious case, I think I wouldn't be confortable in changing my name in any circumstances, doesn't matter the size of the offer. I believe our names are part of our personal history, identity and legacy. Names, like identities and personalities can't be purchased, they are inherited.
However, that is just me. I'm sure other people would see no issues in earning 2000 btcs so easily like that. That would be a life changing.
If we go back 12 years to do this, surely no one will do this because then this 2000btc, we only need to spend a small amount of money can buy it or can get it for free at the faucets.
But if we're talking about the present, I'll consider you a more odd case because 2000 BTC would be worth millions of dollars, and maybe we'll do our whole life and never get it. Changing your name won't be so important, life now matters how much money you have and how your life compares to others. This society is like that, if you are just an ordinary person, no one will care about your name.
