It's not the open floor plan office that's the main cause of the problem for DnD type work, nor are offices with doors a general solution.
It's all about policy. A separate office with a door doesn't do you any good if every ten minutes someone drops by to knock on it. A private office also doesn't help if you're constantly bombarded with "urgent" messages from various people and are expected to instantly reply.
Most of the issues can be solved by simply implementing reasonable policies. Can't deal with the noise of an open plan office? Provide ANC headphones. Need time to focus? Define binding "focus hours" each day during which no meetings are scheduled, no messages are sent, and people are left alone. Keep the inevitable exceptions to an absolute minimum.
In addition to that, it also helps to have separated spaces (e.g. meeting rooms) available that can be booked for DnD sessions if the need arises.
I always see noise cancelling headphones put forward as a solution to noisy office environments . . . I don't want to wear headphones. I don't want to be cut off in my own bubble. I want to be connected to my environment, and I want it to be a nice place to get my work done.
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.
And some people don't want to stop interacting just to cater to you, and some people want you to answer their question immediately so they don't break their flow.
And I have sometimes seen people saying things similar to you, and then being loud or distracting when it was more convenient for them.
I understand your position, but as usual with these discussion, everything seems to always centered about "what I would prefer" rather than trying to understand everyone's needs.
