You sound like the kind of person who doesn't prepare because "oh you know it's so unlikely". In other words, the kind of person who accidents happen to.
You're not only making it harder for bad guys to enter your room, but also for good guys, and for yourself to exit, in case any emergencies happen within your room.
It's not even clear that the benefits of blocking are net positive in all situations (depending on your individual characteristics and the environment, eg if you have a chronic illness and are in a relatively safe location), but the more general point of the post was that you should do a cost-benefit analysis (ie is the risk reduction worth the effort?), not look only at the benefits in terms of risk reduction.
No effort from me.
Like everything physical, it takes up space.
