It can't be scientifically proven. Nothing can.
People don't care if it's scientifically proven or not, they care if it works. If it didn't, it would be becoming less popular, not more. The 'fad for this shit' has been going on for around 5000 years (that we know of, and probably longer)
You don't seem to have fully read the Wikipedia article that you're using to back up your point:
'Two separate 2016 Cochrane reviews found that acupuncture could be useful in the prevention of tension-type headaches and episodic migraines'
'A 2014 review concluded that "current evidence supports the use of acupuncture as an alternative to traditional analgesics in osteoarthritis patients" '
'A 2014 systematic review found that although manual acupuncture was effective at relieving short-term pain when used to treat tennis elbow, its long-term effect in relieving pain was "unremarkable".
'A 2007 review found that acupuncture was significantly better than sham acupuncture at treating chronic knee pain; the evidence was not conclusive due to the lack of large, high-quality trials'
'Several meta-analytic and systematic reviews suggest that acupuncture alleviates sleep disturbance, particularly insomnia'
There's also a good deal of references to the fact that many studies are incomplete, poor quality, and inconclusive.
We need rigorous trials, but it's hard to get funding because you can't mass produce acupuncture.
But enjoy your 'science' and keep on popping those pills. I'm sure your bias won't adversely affect anybody.
