Well as unfortunate as that is the sad fact  that we are all going to die whether by drugs drinking  or a bus  a sudden heart attack. We all will die and people will be sad  and because of that is the reason to live wild and free but mostly just happy whatever gets ya there .  Sorry for your loss but while your sitting there all sad you instead could be celebrating the fact that you are still alive and hoping to go out with a bang instead of a whimper  . Better to die regretting what you have done the die regretting. The things you didn't life is short take big bites mo
The only inherent wrongness of hedonism I can think of is that it largely requires everyone else keep the system running. We cant all fuck and drink to our hearts content because certain aspects of society require discipline and control as a standard.
But really I think there may be some confusion. People don't dislike hedonist for it's inherent failure. For instance I don't care if you're a hedonist in particular, as long as you don't work for me, as long as I'm not the friend you call to bail you out and as long as you don't walk around blaring music. This is because hedonists have this annoying habit of doing what they want first and dealing with the consequences tomorrow. Which is a problem if you rely on me or I rely on you. I'd wager most people who are 110% done with hedonism are just tired of being the one to clean up a hedonist mess. 
I think your view is the widely accepted one. Go ahead and be a hedonist, just do it as far away from others as possible >

To truly maximize the amount of pleasure one can have in life would require a regular income, stable housing, healthcare, quality food, etc. You can be a hedonist and a productive member of society. >

My friend lived like that, and now he's dead. His death, directly related to his hedonistic lifestyle interfered with my life, and more-certainly the lives of his parents and brother.
Nobody lives in a vacuum. All of your actions affect someone.
Even if you don't die, there will be people worrying that you might, which is interfering with their lives.
