Monero is almost only used to buy drugs on oasis and alphabay, this is very problematic opsec wise.
Imagine if all the europeans drug dealers had a different kind of cash called moneuro . What will happen when a dealer try to exchange his moneuro for euros, the clerk is gonna look at him funny same if someone try to buy some moneuro off of him. Not to mention that the shop will have more regulatory scrutiny. Exchanges accepting monero for fiat will most likely get shut down sooner or later . Monero is good as an intermediary solution to break the chain but if you try to cash out or buy monero you will instantly be flagged as being involved in illicit activities. Bitcoin on the other hand is used for everything so you won't immediately get labeled as a drug dealer for exchanging it.
Monero has literally only been on for Oasis and AlphaBay for a matter of days, and already you're consolidating its entire two year existence as if it had always been on Oasis and AlphaBay.
More importantly, you're just parroting the same kind of arguments made against Bitcoin by the traditional financial order, which brings a kind of "Animal Farm" element into play. It's worth being cognizant of this.
Change happens - it's just the way the world works. All that remains, is whether the change is good, or whether the change is bad.
Monero is clearly a change for the good.
