It's not the solution (plus they have an "aware"-mode that doesn't shut you off completely), it's a possible solution and a rather simple and cheap one at that.
Depending on the circumstances it isn't always possible to provide a work environment that everyone considers to be a "nice place to get work done". Some people don't mind background chatter, others can't concentrate if someone as much as coughs somewhere.
It's also a bit hard to not being being cut off in your own bubble as you put it, while simultaneously wanting to be connected to everyone else. Being in a separate, single desk office is no different from being in a bubble in that sense.
