Appearance modifications work well when you only have a few character models. With the wide variety of characters available in multiplayer, it would be impractical from a development perspective to make different clothing options for all of the characters (Pig Josh and Luisa Fortuna would not want to swap clothing, for example).

Limited weapon customization is more practical - like if when you made a gun "golden" you could go to the outfitter and choose from a handful of design options. That would also give people who don't like the golden appearance an option to select a different one.

I think there's some room for customization of existing horses with different saddles or minor appearance differences, but full-on breeding would be impractical due to the number of possible variations.

Having economy in multiplayer implies having an inventory to enable income from skinning and plant gathering and for tracking purchases, etc. I don't see anything wrong with that, but for me at least it wouldn't add much to the game - the only time I have an issue with running out of ammo is if I get stuck in an alley in Blackwater with a bounty and get surrounded. Otherwise, there's enough ammo chests that they would usually be more convenient than shops. If there were money in multiplayer, what would happen if another player killed you? Would they loot your corpse and get all your dough?
