You just can't beat nature.
We are mammals after all, and we're going to have fur. Trying to cure hair growth is like trying to cure homosexuality. You might get rid of it for a while ... but it always comes back.
As someone who not only was hairier than most of the people I knew, but someone who went through puberty earlier than everyone I knew hair had for many years been the bane of existence. Having spent my early childhood in the hairy 70s I found my post pubescent hairiness in the tanned and waxed 80s a source of shame. My dread of body hair had a huge impact on my esteem and sex life. I was probably manscaping
before the word had been invented.
Years later I find I couldn't really care less. Recently I did some grooming and I thought Ugh I'll never do that again. Over time we learn to accept ourselves more and that means our bodies and everything else. My taste in men has changed -- I like 'em hairy now, and unless you're into twinks I've found that's a pretty common change for older gay men to have. And because I like them more, I like me more. It seems sexier to me now to simply "own it" than to have it and try to change it. And thank goodness we are living in a pro-beard pro-hairy climate and there are all those wonderful hairy bear sites for our hairy young gay boys to see and understand who they are as men.
If science invented a way to permanently
remove hair then when you are older and entering a new phase of your life, one where you may not only tolerate your body hair but actually love it, it would be too late and you couldn't get it back. Constant hair removal may be a pain in the ass now, but one day you'll be thankful for the failures of science.
