There are two related but very different metrics in play with number of encounters. Deadliness and resource management. And the first issue gets a lot more focus.
Deadliness is HP attrition and related (HD spend, etc.) I agree this can be balanced by doing deadlier encounters. I don't think many are arguing the other way, so we'll just accept this. Everything further down has nothing to do with PC survivability.
The other is resource management, or to be more specific, the balance between primary at-will classes and primary long-rest classes. They are hybrids, like the barbarian and the paladin, that combine aspects of both and are somewhat in the middle.
It's the little cousin of nova-ing. Basically that having fewer total rounds of combat per day means more actions casting slots vs. casting cantrips. And those rounds of combat broken up less also means more efficient use of slots for long-lasting spells - say having a buff up in all combats using 3 slots instead of 6, and getting to use those extra actions not recast it in a different combat are instead used contribute in other ways.
(I am assuming everyone agrees that without a class feature like warlocks can take boostering them, a cantrip has less total effect on a battle than a on-level or near-level spell. If not we can have a tangent to discuss that.)
What it comes down to, is that if you decrease the total Actions a character takes over a day's worth of combat, for at-will character it's a linear decrease, with their actions being roughly even. For casters those actions are removing more cantrip Actions than spell slot action, for a smaller total reduction in output over the day. Actions filled mostly with levels spells average more than Actions with more cantrips added into the mix. So their relative power per action increases.
This is most easily seen in play. Really, it's a dramatic difference. If you normally run 2-3 encounters per day, run a few days in a row of 11-12 encounters - the other side of the recommended amount. Tell your players about it ahead of time so they aren't blindsided and you can have a good test. You will see a dramatic change in rounds using cantrips from casters, and a real feeling of power from at-wills that can contribute equally every round, no matter how many preceded it.
Try it yourself, and then say it isn't true.
