The "people won't ignore it" and that they'll use it for bragging rights (is that seriously even a thing people care about????) argument works as an argument against having a pp system at all. The current pp system favors people who play certain types of maps, regardless of which game mode you're referring to, just like an all-mode ranking system would favor people who plays all modes. An all-mode ranking system would actually be harder to exploit for bragging rights though because you can tell so easily if someone doesn't play one or more of the game modes - having a 1pp play as a top performance in some mode tends to make it obvious, for example. This, of course, is assuming that people actually care about using rank for bragging rights rather than for a fun bit of competitiveness. Which is really really silly.
The "x pp in one mode is not the same as x pp in another mode" argument is true and I stand by what I've already said in this thread that the pp curves for all modes would need to be smoothed out before this would be a good idea. I do think it would be a good idea when that happens though.
