The concept of jobs in era is for people to actually put effort or struggle in them, like any real life job... Nothing is ever easy, you gotta work for it bud.
And of course everyone gets pissed when they get their mushrooms stolen, or shells picked, or even when they get killed during a car mission, but I mean thats kind of the point, to make the jobs a little harder. If you really expect a machine that grows mushrooms just for you or spawns trash for you then you would be expecting every player to own a bar technically..
I'm sure the staff doesn't want you to get pissed, they just want the best for the community.
Oh and before you say that the machines will be sold at a very expensive cost, even if they are it will be very unfair for players to own them, since they can just afk and wait for the trash/mushrooms to appear while others are working their a$$es off.
I am sorry but I just don't see this getting implemented x.x
