The reason people have more respect for the 4th amendment than the All Writs Act is because the Constitution is the basis for ALL federal law in the US. It grants powers to the federal government, and nothing not specifically enumerated can be the subject of a federal law.
I'm not really concerned with the age of the All Writs Act per se, only its constitutionality. If it violates the Constitution in any way, then those portions that do so violate it are unenforceable. It wouldn't be any more or less constitutional if it had been passed last year.
