You're right that for most people the fastest route to advancement requires changing companies, and you're right that future companies are unlikely to care (much) or know (much). But you're wrong in your conclusion.
The (good) reason to take work home is not to suck up. That's crappy strategy. The good reason to take work home is that it's practice. The sooner you put in the hours, the sooner you can get-and-keep the better jobs. Obviously there's a limit to personal endurance, and so just pushing yourself to grind out 80 low-quality hours per week is insanity. But taking work home, selected with the intention of improving your own skills, is often good advice for getting ahead. Hustle correlates with prosperity.
You're right, though, that if _I_ take work home, that you, user5994461, are thereby disadvantaged in the market. Thus I assume that your imperious demand that others not pursue career success is a cynical ploy to improve your position.
Indeed, you working more is lowering the bar for employers, you're helping them to pay less and abuse their workers. (Let's ignore for a minute that I don't work for these employers).
Since career success is linked firsts and foremost to negotiating offers and following a career plan, I demand that you negotiate better and follow a more aggressive growth plan! It will give you more returns for less efforts than long hours.
I am on the high end of the spectrum, I actually need others to pursue their career success better in a cynical ploy to improve my position. ;)
