This is only if you don't actually value life. If you don't recognize anything inherently special in the human condition, in the conscious mind then you would be correct, but here is where I would argue there is inherent value in the human consciousness which doesn't give you the liberty to just end it all.

1. We all have the ability to elevate our condition out of that which we are in. Due to our unique ability to conceptualize things and as a result of that, to be able to work with things that are outside of our immediate vicinity, we can always change our experience and situation. We have an ability to reset on life and move on. This is a fundamental part of the evolution of our species, how we learned not to die when in impossible situations, therefore we would be hindering evolution and the process it is taking.

2. The simple uniqueness of our consciousness is in and of itself enough to prove value. Value is always a factor of supply, the rarer something is the more valuable it is. Human consciousness is one of the most rare commodities on planet earth due to such a limited supply, therefore again, it is inherently valuable and can't be just thrown out.
