I kinda agree, but I think it depends on the type of work, and your own personality.
From my perspective it's kinda like a band. Look at the Beatles - they did everything together for almost ten years - and it was that connection with each other that made the band (and as a result, the music) so awesome. The same can be true for business. A team that works together in physical proximity is gonna be so much stronger and have a much better connection with each other.
However, if you're working for a huge multi-national corporation that's so big that you don't know the names of everyone in all the other departments - then you're not gonna get that same connection anyway. In this case, you might as well work in whatever way is more efficient and more comfortable for you. For some people it will be the freedom of working remote - for others it will be the structure of a 9-5 work day.
Some people (mostly gen-y, but not limited to) find the traditional office-culture too stifling. Everyone is putting on their 'professional persona' in the office. Now it's possible to work remotely and instead hang out with 'real' people.
