Liquid apls have been very dilligent in labelling liquid Bitcoin as LBTC instead of $BTC to avoid confusion, i think ecash custodians should do the same by branding their tokens as something other than $BTC
For example Bob's ecash tokens should be $bobBTC and alice's ecash tokens should be $aliceBTC
Free banking theory implies that $bobBTC and $aliceBTC can and should have different exchange rates based on consumer confidence
