Is so called "Bitcoin adoption" pointless and unnecessary?

Everyone is always talking about "Bitcoin adoption" and posting pictures of businesses accepting Bitcoin. But do we actually need that?

I say that because whenever I research anything about Bitcoin self custody, all the advice, even from the vendors a lot of the time, is all like 'only order directly from the vendor, and we'll ship it to you in a tamper proof bag, and use a PO box and get your mail forwarded from there so that nobody has your address'. And then all the self custody advice is like 'and you have to run your own electrum server so that nobody can see what you're doing at all', and 'you need to protect yourself from thieves and the government!'.

And then we're meant to have all these businesses with massive Bitcoin signs, like 'hey look over here, look at us, we have Bitcoin, come and get your Bitcoin here!'

How can both of those things be sustainable simultaneously?

From a security perspective, one of the only things which has improved over the last few decades is that as money has become more digital and more controlled and monitored, it's become harder to steal. And I understand the logic that if nobody knows you have Bitcoin, and all they think you have is government monopoly money that's fully tracked and can be reversed if stolen, and used to catch them and lock them, then they won't try and steal from you because that would be futile. So you'd better keep the fact that you have Bitcoin very private.

So if we have "adoption" doesn't that just mean that muggings and robberies are going to go up like a million fold? And won't even more serious kidnappings and ransom attacks become way more possible?

Wouldn't it be better instead if Bitcoin was only used at the institutional level, or at the personal level for settling large transactions? And even more so if the block reward goes to 0 and only fees sustain the network! In that scenario, it would always make sense to pay high fees for an occasional extremely high value transaction. But for buying a coffee, why not just use the government fake money? Seriously, I'd rather walk around town with my tracked government fake money that can't be stolen, buy a coffee or whatever, and just keep my Bitcoin fully private, but still in my own custody maybe with multisig (although like I said I do worry about how rich people are going to be targeted in future). But you see my point hopefully. Who cares about CBDCs even if your savings are all in Bitcoin. Isn't the most convenient, idiot proof, and cheap form of money the best for day to day transactions? So why do we need Bitcoin adoption? I don't go around spending gold bars, why would I go around spending Bitcoin? Am I missing something here?
