Exactly!

And as an addition, we can also squeeze more inputs and outputs in a single transaction using SegWit addresses.

Quite anti-Mining? Caring too much about the price? (uhhh, I'm guilty too)
Bitcoin hasn't been paying miners to process transactions, they simply mine what's profitable.
This isn't the only SHA-256 coin out there, and the total hashrate won't affect the number of transactions per minute, just the network security.
Quitting miners: not much of a problem considering on how Bitcoin was designed.

The one who got a recipe of failure are Bitmain and ASIC Manufacturers, but they are currently bathing in profits for now.

The center of your attention based on your assessment should be: Bitcoin with low Network hashrate will be much more easier to attack with easy to access hardwares if/after most of the miners quit.
