It's like this. Larian is dealing with two types of people: those who want immersion and those who don't want to be bothered by such realism.

For the ones who like immersion, you can avoid using Fast Travel, Fast Sell, etc. Jog to the grove every time, talk to the merchant and sell your gear.

For those who don't like this, THAT was why I came up with the Fast Sell option and such. If you aren't in some danger zone, allow players to Multiselect items and click fast sell. Super easy and you cut out all the extra steps of doing it the immersive way.

Same with Send to Camp. Its for those who don't want to do the immersive approach.
