You’re mixing up feet and meters. The death zone is at 8 km, i.e. 26k ft.
2100m is barely mountaineering, you can bring grandma and the newborn hiking there and at most you’ll notice a mild shortness of breath.
In fact normal cabin pressure at cruising altitude is equivalent to 7000 ft. Besides a lot of ear popping most people don’t even notice it, though mild altitude sickness (i.e. a small headache) is possible, but ultimately harmless.
ah, that explains my confusion - thank you for clearing that up!
