There are very few unbanked people in western countries, and so its natural that it would be unusual to come across those use cases there. There are in fact services that will act as a glue between the bitcoin ecosystem and "fiat", such as bitrefill which allows you to buy gift cards for many different stores using bitcoin. However for most people and every day payments there isn't really a compelling reason to try to use bitcoin. In fact, if you have both bitcoin and national currency, with rising prices it makes more sense to hold onto the bitcoin and spend the national currency.
There certainly have been some countries where stablecoins have gained in popularity. They are a little easier to use than bitcoin and prices are more stable. It tends to be in places where governments are not heavily enforcing against their use, while at the same time the local currency has been unstable, such as in Argentina.
The downside with stablecoins is that they rely on trusted entities to maintain the peg, whereas bitcoin enforces its own scarcity and trades at its own value.
I don't really think its responsible to go around telling people that bitcoin will gain in value, but there are certainly many people who believe this to be the case, and the pool is growing. I think the key value for this community is that we have something which is easier to transfer globally than a hard asset like gold, while being independent from particular jurisdictions such as the US, EU or China.
And yes I see the lack of awareness in bitcoin community about the extent to which it has become the defacto standard for internet scammers, who trick vulnerable people into depositing their life savings into a bitcoin ATM using various methods. You can see many examples of this on kitboga's youtube channel. At least, he has been able to work with some bitcoin exchanges to fight back against this in a small way.
