To be honest, I don't see Bitcoin as everyday payment system for small things, like cup of coffee. High fees at moment are not reason for that, I believe that BTC developers will solve this with LN or some other thing.
Problem to buy coffee in my view is because price is too high and it will be higher in future.

At moment of writing 1 USD is 0.000108785 BTC. It is not ease to put all those zeros when you are buying something and it will be more zeros if price go higher. I think that average user don't want to do this and there are other cryptos for small payments. You can still pay for cup of coffee with BTC if you have Bitcoin VISA or Mastercard but this is not Bitcoin payment, that is fiat payment after card provider convert your BTC to fiat.
Maybe Bitcoin price in Satoshis can solve this and I have herd ideas for that but I don't think that it will be easy to implement that.

My view of Bitcoin is that it is best store of value and payment system for transferring large amount of money and buying expensive things like houses, cars,etc...

Somebody can ask why BTC, why you don't use some other cryptocurrency for that?

Reason is simple, BTC is most decentralized (not as I would like) of all, it's brand is well known around the world, and it doesn't have leader that you can influence on.

Satoshi's leaving is best thing he could do for BTC dough he's tech skill would be useful for sure and it wouldn't be more pronounces of he's vision that I hate a lot.
If he is around somebody(governments, many bad people) could force him on something, so this what he did is best for Bitcoin and him.

And use case for uncontrolled, free money transfer is huge.
Imagine how rich people from Russia felt after USA and EU put sanctions and froze all money that they have in foreign banks.Nobody want that he's wealth depend on some government's will. With Bitcoin you don't depend.

How would Julian Assange defend himself without BTC? They froze all his assets but BTC they can't.

Swiss banks were forced to open their accounts after 2009. crisis and now Credit Swiss, one of their biggest banks is not profitable for last 3 years. Why would you keep your money in Swiss banks if you don't have any benefit comparing to other banks.
So there are Falkon private bank and Vontobel bank, who firs have aloud keeping bitcoin on account and I am sure that more Swiss banks will follow that.

As a store of value I agree with opinions that you can't just HODL, you need to spend that BTC have value. There is more and more houses bought with BTC and as I wrote, BTC is perfect for buying expensive things. Again story with zeros, it is easier to pay 107 BTC than 1000000USD.
