The vast majority of people that visit national parks stay at campsites that are attached to parking lots, that have running water and bathroom facilities, and that have at least some cell reception. Many of these are attached to well marked, well traveled trails with amazing views that make for excellent all-day hikes. You don't need a PLB to visit one of these camp sites or hike some of these trails.
But if your off-the-grid campsite is a 30 hour hike from the nearest road, and half of that hike includes a mountain scramble and a trek across a frozen alpine lake, then I'm sorry, but you can't responsibly plan such a trip in 2020 and not carry a PLB.
Between your clothes, boots, jackets, shelter, backpack, food, fuel, cooking gear, and navigation equipment, you're likely carrying at least $1000 of equipment. You can figure out how to borrow a PLB.
Spending days flying circles around a vast wilderness where somebody might have gotten lost is expensive and time consuming and takes resources away from other people who might need them. It took 20 years to get Sarsat up and running and for PLBs to get cheap, and now rescue organizations all over the planet are asking you to please, for your sake, for theirs, and for the sake of other people who may also need emergency services, carry a goddamn PLB if you're going to go off the grid.
Contrary to popular belief, going out into the wilderness is not about eschewing all technology. You still need to be responsible, and today, for certain activities, that means carrying a tiny piece of emergency equipment at the bottom of your backpack that you hope to never have to touch.
