Once a public bitcoin address is linked to you, you can never hide from it. To spend it, everyone will be able to know how much you spent and when, and sometimes to who. But when a public monero address is linked to you, nobody can know how much or where it went. You can continue use it privately. Monero is far superior to bitcoin in every way except it lacks the popularity network effect

Hence never re-using addresses, this is like basic knowledge every bitcoiner knows and gets told from day one, are you new here?.
Also if you're going in and out of monero to btc it gets pretty easy to trace you if you're not careful.
Dude, no one is going to do that. 99% of users are going to re-use Bitcoin addresses and not practice good privacy habits. Privacy on Bitcoin is like trying to convince everyone a screwdriver is also great at hammering nails. Any sane person will just use the right tool for the job. You can still use Bitcoin to save if you want.
The last part is a flaw of Bitcoins' not Monero. Don't go in and out of Bitcoin. Spend Monero directly - problem solved.
WTF are you talking about? Literally every single wallet lets me generate unlimited address from a single address. Even coinbase does this...
It's optional, they can continue using the same address. In fact, it makes more economic sense to do that. Doesn't stop users from consolidating either. Like I said, lots more ways to mess up privacy on Bitcoin.
Not reusing addresses is actually difficult and complex to do, and still traceable. And if you manage to join mix your coins in several rounds, at greater expense, maybe, just maybe you are safe enough. But who wants to do that every time they buy something. And if you aren't going to do that then you might as well just use Swift/vise/paypal since you will be needing to do that anyway in day to day purchases., and -this is the saddest part - its cheaper!
Bitcoin privacy sucks so bad, there are still other advantages to Bitcoin, but nobody should be under any illusion thats its private or cheaper than fiat (unless you are using it to send large amounts and never cash out)
