I agree with this. You can have an entire 3 hour game session without ever actually mining, shooting, scanning, hauling, trading, hunting or any of the normal game functions. You just stay in supercruise. You can absolutely do that, so it's a part of the game.
But let me ask you, when you're in a system that has a station just a few Ls from the nav beacon, and another 400K or so Ls away... would you supercruise back and forth between those to trade or would you jump out of the system at the 400K Ls station to an adjacent system, and just jump back in to cut the time of travel? I've jumped from 1200Ls, high wake out, then jump back to the same system to avoid the time drag of planetary gravity. That's me choosing 30 light years over 1200 light seconds. That's 30 light years being traversed in less time than it takes to cover 1200 light seconds. It saves time.
If you don't supercruise back and forth, if you opt for the high wake instead, you're basically saying you don't want the long supercruise times either. I get the novelty of Hutton, really I do. .22LY is no joke. However, extrapolating that novelty into every supercruise event quickly causes the argument for SC to fall apart.
