How do you take the information that the vendors convert Monero to Bitcoin? These are always personal reasons and not a standatized process. In addition, it is certainly useful to distribute assets.
Do you have any arguments that Monero is not a store of value? In your text, I can't read a single one. Here you have very good arguments why Monero is a store of value: https://localmonero.co/knowledge/monero-better-store-of-value?language=en
And I can currently use Monero wonderfully to buy super many things. Because Monero, unlike Bitcoin, is currently actually used as money. Air tickets, hotels, electronics, coupons, used stuff on several monero based markets, digital goods and much more.
All your points are out of the air, because you actually have no idea what you're writing about.
