I'm not sure what prompted you to pin this view on Western philosophy in particular, as plenty of other cultures and philosophies value asceticism.

Also, it's not like hedonism doesn't have downsides, such as the common effect of needing ever more extreme stimulation to achieve the pleasure you could once achieve with less extreme stimulation, leading to a spiral of debauchery which often has deleterious consequences to the hedonist, even if you overlook the pain and suffering they often have to cause others to please themselves.

There's a reason that so many philosophers throughout history and from different cultures have advocated moderation, but the hedonist has trouble moderating themselves because then they have to do things that aren't pleasurable.

There are also advantages to asceticism, from the (debatable but potentially valid) spiritual benefits, to achieving self-mastery and control, not getting too attached to pleasure or comfort when it could be easily taken away from you, etc...

In any case, the case for hedonism is far from a slam dunk, and you'd really have to do a lot more work to make that case convincingly. Just saying that "Western Philosophy" is against it is not very convincing.
