The laws belong to the people...?
Experts in Con Law aren't "people"? Scalia and Thomas aren't "people"?
So it is the "people" who should decide Supreme Court cases? So if the "people" decide that that the Constitution protects the right to abortion, then Roe should be upheld?
No they are not. They are precisely not "the people". They are the government, the elite, the rulers.
Stephen Breyer used the same argument as you to justify his appeal to foreign law and to reject originalism. He was "the people" deciding for all of us.
The Supreme Court did not get this wacky when its members were often chosen from the ranks of retired Senators.
