The biggest problem with it is that it's kind of a safety issue. If someone has health problems that might mean passing out or injuring themselves, like a seizure disorder or allergies, then a physical barricade like that might not be the best idea. It could also be a problem in a fire for the same reason. On the other hand, it could protect someone in the event of a break in... Basically, it's a matter of considering your individual situation and needs, then weighing the pros and cons.
