Remove PulseAudio if you want. Don't ask distros to remove it, though. I don't know about you, but I prefer having modern conveniences like USB hot-plugged audio hardware and Bluetooth headsets just working without having to restart my entire desktop to get applications to reconnect to hot-plugged ALSA hardware devices.
I like having software sound mixing that actually works. dmix never worked right for me. Not once. The few times it played sound, it played like crap. PulseAudio just works (except for Flash). Sounds great, no skipping, just works.
You have bugs you run into, I don't. Your solution is to throw away features a lot of people need to go back to the stone age where the shitty poorly-coded drivers and apps managed to narrowly avoid each others' bugs and happen to work. Intelligent people's solution is to go "OMG bugs! Let's fix them!" And then we all have perfectly working audio all the time by default.
File bugs. Or turn PA off. But don't scream about how PulseAudio is useless when it solves problems that ALSA never has and never will be able to solve, like hot-plugged devices.
(Personally, I still think ALSA was a mistake. These days all it amounts to is Linux being incompatible with every other UN*X OS's sound interface, practically _forcing_ developers to pick a sound server or wrapper library or some such just to have their damn app work on more than one distro.)
