Not at all true... I am far sighted, since most of what I look at, including my monitors are more than a few feet away, I tend to see them fine.. my phone is the only device I really have a lot of trouble with. I run in "extra large" font mode, and set my browser zoom to 125%... even then many sites, I have trouble seeing stuff... if there's an image that isn't full width, then I likely can't make out the detail....

Not being able to zoom in to at least 2x, is a pain... if your content doesn't overflow, then sure set the minimum zoom to 1x, and the max to 2 or 3.. but disabling it altogether is just painful to experience... and many of the "suggestions" to fix mobile scaling include disabling zoom. I'm not even that old (40), but I imagine the problem is worse for people well into their 60's.

If you're using a font-size less than 12pt, you should emphatically NOT be disabling scaling... Unfortunately many sites/apps do just that, and often don't respect the usability settings in the OS (facebook on android was particularly bad, as in too small, before I uninstalled it).
