Ok, maybe so, we'll see what happens, but in the meanwhile users might need the combination of these properties *today* and Monero is the only thing that offers them at the moment.
Ecash is great privacy, really the only real contender as far as privacy goes, but it is custodial and mints can covertly print tokens unbacked by the base asset (Bitcoin). Not censorship resistant or permissionless en masse: if the mint disappears, or simply refuses to exchange or redeem any tokens, your eCash instantly becomes useless.
