One thing I often hear is how bitcoin should become a fully anonymous cryptocurrency. No, it shouldn't. If people want bitcoin to truly become mainstream then making bitcoin fully anonymous would destroy that goal. I believe in these types of currencies, such as with Monero whom I support fully.
It would if there's consensus, but you are free to your opinion.
An important point. Because privacy has the potential to be somewhat contentious,
it's difficult to say how many privacy-oriented features will find their way into the base protocol.
I believe "there's consensus", and "needs a hard fork" will never happen in Bitcoin in my opinion.
There are many opinions, but we'll have to wait and see what rules users choose to enforce. Some people have also speculated in the past about "privacy layers" that can be built separately and users can opt in to those if they desire more anonymity. These could potentially exist even if others disagree with them.
Yes, like the Lightning network, the big blockers hate it. Or CounterParty, the Core developers hate it.
