Just to clarify: there is no other coin involved, so we haven't created a shitcoin. It's just a mechanism to stabilise a part of your Bitcoin holdings with respect to USD. It's all sats under the hood.
And to your first point, I think giving people the option to do something that they already do (trading) in a way that respects the self-custodial principles of Bitcoin is hardly pushing people towards greed. Whether you like it or not, people will trade with Bitcoin and if they do it on custodial exchanges their funds are always at risk.
