Agree thats silly. Just spend in xmr. The fact that people don't use XMR isn't an argument against its technical superiority. The network effect is driven by fud/propaganda/lies/investors etc.  None of which are defensible reasons to use Bitcoin, even if they are practical reasons. 

 Why would somebody want to hold asset that's less secure? 🤔 

 Monero security is fine. Digital fiat is a million times less secure (your funds can be frozen, confiscated, no privacy from banks and governments, and rampant unpredictable inflation), yet I'm sure you and most people hold some. You also don't have to hold Monero if you don't want to - just spend it 

 Yes, I would rather own some Monero to buy my groceries for the week instead of cash, but that's not possible and probably never will be.

But how would one just spend Monero without holding or trading something for it first? 🤔

Monero is actually much less secure than Bitcoin on multiple levels. 

 I can't buy groceries with Bitcoin directly anywhere around me either so what is the difference? You act as if everyone is using and accepting Bitcoin when they're not. Most people still don't know or care about Bitcoin.

If you're holding some fiat right now (and I bet you are) then it is quite hilarious to nitpick about Moneros security. 
There is a ~$3 billion bounty for you to break it's security. If it's so weak, then go get it! What are you waiting for? All for you! 

 The differences lies in security and assurances. 

I don't want to hold something that's less secure for most of my wealth.

I could think of having some privacy shitcoin or fiat for my weekly groceries, but only fiat is accepted atm. 

 That has nothing to do with Monero

Of course Monero can't guarantee privacy if you leave it. Almost all the negatives you list are consequences of Bitcoin (cost, potential privacy failures, time consuming swapping) not Monero

You have to use Monero directly 

 the problems of bitcoin is not moneros concern 

 But Monero is not a solution
