This is such a backwards take. You are ignoring that the system you cite as evidence that secure systems with backdoors can be designed and protected from random access has not been perfectly protected.
And you say it's stronger now.
Ok, so which country or neighbor is going to be the one to hack our national encryption system with a back door the first time? The second time? The third time? Before we manage to get it right (which we never will), what damage will be done by the backdoor? Probably something like Salt Typhoon, which you also conveniently ignore as a counterfactual to your claim.
