What I mean is this, for example;
Let us say I am a theoretical physicist working on a project in researching the M-theory. Let us say I am assigned from a research center in Davis and I live in Tahoe. Can I go to the research a couple times a week, spend a lot if the their those couple times, get the work and live in Tahoe? Get the equations I need to work on for the rest of the week in at home or some center in Tahoe for example. Please note this is only an example, I am not saying that I have to live in Tahoe or I have to work for Davis, just an example.
BTW, if you want to work at a top research center such as Los Alamos wouldn't you get a job most likely if you have a PHD from a prestigious university?
During the early 90's, in one of the many economic slowdowns in the US, there were reports of physics Ph.D's from "prestigious universities" driving cabs for a living. When you look at a few anecdotal examples, you see that they were high energy physics theorists or astrophysicists, etc. Yet, at the same time, I know for a fact that freshly minted Ph.D's in Medical Physics were getting job offers even BEFORE they finished their program. Condensed matter physicists who know how to fabricated thin films using laser ablation were getting snapped up by Hewlet Packard and Xerox as if there's no tomorrow.
The example you gave doesn't help your chances of employment. While being a theorist may allow you the ability to not have to be on site physically all the time, you are also cutting down considerably your chances of getting employed in the first place. How many theorists from prestigious universities graduate EACH year? How many job opening for them do you think are available? And how many of these do you think are in String/M-Theory? At Argonne, there are ZERO number of string theorists being employed, even though the high-energy theorists do dabble in it on the peripherial. However, most of them deal with the theory that is related to the experimental effort of the division. This makes a lot more sense, at least to me. US Nat'l lab are reviewed by our "owner", the DOE, every single year. You have to show what you have done, how much of what you have promised last year has been achieved, and what do you promised for the next year. Under such condition, String and M-theory proponents have a very hard time to justify their existence. It is why you won't see such work being done at US Nat'l Labs, only in universities.
There is also another issue here that you have neglected. When one is employed as a physicist, one does not just do physics. One has other administrative reponsibilities. This includes supervising others, especially if there are grad students and postdocs. There are responsibilities in getting external fundings, administrative decisions (one usually has been drafted into one or more committee in one's division), etc. etc. Practically in all such cases, one needs to be on site physically to fulfill such responsibilities. In a series of essay titled "My Physics Journey", I have tried to convey the daily grind that I go through, and this includes both physics and non-physics responsibilities. I believe this situation isn't unique, and that most, if not all, physicists working either in a university or Nat'l Labs go through the same thing.
In any case, unless you are a BIG NAME physicist, you would most likely start your career as a postdoc and work your way up. I have never, ever seen or heard of a physicist working his/her way up being able to do what you would like to do.
