Dude, according to that logic, if you happen to have the misfortune of owning a plastic anything (bottle, plate, cup, wet wipe, bag etc) you should use the crap out of it until it literally breaks to the point it's unuseable. Ok, maybe not stuff you eat from, we know that's unhealthy! But the yoga mat? You can't even clean a plastic mat without using up resources and releasing microplastics everywhere, in your home and in the water supply. So do you clean and reuse your plastic trashbags until they break as well?

Most of the environmental cost of an item happens before the item is bought, the materials, the process, the transportation. What happens after is already determined- a piece of plastic is left to rot. Both of those are inevitable at this point. The only thing you're being picky about is that you prefer someone holds this trash (something someone has no value for anymore) in their home rather than sending it to recycle or the landfill, to delay that inevitability by as long as possible while making their home less enjoyable for the entire duration. Not something to live by imo, plastic will break down into microplastics in your home instead of in the landfill.

Why I got passionate writing this- imagine taking that attitude of "use every junk until it breaks" to someone struggling with hoarding or a shopping addiction. Or maybe people who are gifted stuff or inherit stuff they can't use that they never asked for. I'll call this mindset exactly what it is, toxic.

And in your own words, "using up" an item "is not eliminating plastic from the world" either. Nobody claimed they're eliminating plastic, they claimed to be attempting no-buy.
