I have had a pair of Jabra earplugs and boss headphones combined for over 7 years now.
That's just anecdotal, that doesn't mean that other products or other users haven't had any issues.
It's a product issue. Not a Bluetooth issue. As mentioned many times.
As I mentioned before, I don't care that whether it's a "Bluetooth" isssue or not, it's a common issue experienced with that class of devices. The point is, the issue exists, whether or not it's a fault of the actual Bluetooth protocol isn't the point here.
My jabras are going strong despite being almost 7 years old. [...] Maybe I'll have to replace them once they hit the 10 year mark.
Again, anecdotal. I highly doubt that your battery would last for 10 years (and still have any useful capacity), which would be going against the well established averages for lithium ion. Many popular wireless earbuds, such as the Apple Airpods, have a lifespan of only 2-3 years.
The fact is that most wireless headsets will turn into e-waste - and dangerous e-waste at that - in a much, much shorter time frame compared to wired. That does not sound okay to me.

That is very personal don't you think?
And yet, it's still an additional activity that one may not want to engage in. It's a pretty common complaint, so it's not as personal as you think. Lots of people avoid wireless products for this reason alone.
I can't replace a wire on my wired headset to my computer.
And as I said before, any decent headset will have a replaceable wire. But even if you can't replace or repair the wire yourself, it's typically not an issue for a repair shop to do it, and it's pretty cheap too. Whereas it may not be that straightforward or cheap to replace a built-in battery - for starters, your repair shop may not even have the battery in stock (especially if it's a 7+ year old, not super-popular model), assuming someone even makes a replacement battery, you'll need the shop to order it in, which can take a long time, considering most airlines prohibit shipping loose batteries in cargo - which means that the battery will need to be shipped by land and/or sea. And even then, it doesn't solve the e-waste problem.
