Maybe, but it's not the story that "writers" wanted

Just a side note for those who think that it would be cool to build V's rep before receive the call from Dex :
Dex search two gonks ready to do everything possible (even the stupidest heist ever...) to be famous, rich and reach the major league. Indeed, he find these two gonks with V and Jackie.
So Dex search two mercs with no rep
What do you mean? That is LITERALLY the story that the writers put together.
Origin > Jackie > Heist > Post-Heist Content > Ending
People are saying they want to play out the Jackie part and push the Heist to Ending part further down the road or shorten it.
As for your simplistic summary you could do that with any game or any story.
"Easy, about 2 minutes to resume V's arrival in Night City, V become a merc, meet some characters, all of that with help of his/her new buddy, Jackie. No need to play it to "show" these few events."
This could easily just be...
"Easy, about 2 minutes to resume Geralt's story, he meets up with some characters, all with the help of his two old love interests, Triss and Yen. No need to play it to "show" these few events."
Because The Witcher 3 is really a story about Geralt finding Ciri and The Wild Hunt, right? So no real need to include all of that other stuff that people absolutely adored about the game and connected you to both the main and side characters.
