Most organizations spend an enormous amount of money on offices. Offices can be argued are temperature-controlled, resource-hogging (if not LEED certified), calibrated, noise-attenuated (sometimes), free of most distractions (possibly pre-Facebook [1]), constrained, regimented environments with strategic floor layouts designed precisely to get people who are paid a salary to focus and produce value for their company. Schools are similar (witness the backlash against home schooling). Focus is very important but as the OP posits - it is a matter of learned self-diligence and control. [1] The companies I've heard of that block Facebook, personal email et al. (e.g. financial institutions) typically make it near impossible for work to be brought home (which can be good - separation of work and home).
