Opinion on "Drinking Song"

The first line of the first stanza initially put me off to this poem because it feels so cliche. For some readers, the line "I want to die in the saddle" creates a point of familiarity because it is a common theme for songs and movies. When I read it, I heard someone who gave up on his existence because of the poor personal choices he made. Of course he wants to die...nothing is more painful than navigating a horse while nursing a nasty hangover. The next stanza, "I'm going to be a child about it and I can't help it, I was/born this way" frustrates me because, again, he's making excuses for his circumstances. I wasn't born to do math, but I found a tutor and pulled through, so don't give me that crap. And, if he's going to act like a child, then it may be in his best interest to stop drinking and get a job instead of fishing. Oh...but he had a job. However, he quit because his wife left. Well, let's see here, losing a spouse probably means you're losing half your income, so it might not be a good time to quit. Besides that, she left because he's a childish alcoholic. Maybe he should be evaluating his actions. "whiskey is good for the brain." If you're trying to pickle it! "What else am I supposed to do in these last days but fish and drink?" How about apologize to your boss, find a job, and beg your wife for forgiveness?
I am fully aware that this poem is a token to creative license, and it captures images and utilizes the words perfectly. Also, this is the best example of the form I have been exposed to, but with my inexperience, I need to explain why I respond negatively to certain pieces.
