It saves a ton of time. I’ve worked with clients before and I’ll put a lorem ipsum as a placeholder for text they’re supposed to provide. Then the client will send me a note saying there’s a mistake and the text needs to be in English. If the text is almost close enough to what the client wants, they might actually read it and send edits if you’re lucky.
Somebody tried selling me a locked phone on eBay despite listing it as unlocked. The seller refused to be helpful so I filed a claim with eBay, waited the 10 days, eBay sided with me, got a refund and shipped the phone back, waited for the refund to process, then spent $100 more to buy the same device from Amazon.
