It's really not possible to "store value" if you don't have a high transaction quality. You are storing value for later use which will involve a transaction, not just to watch the "value" climb.

So if you want high quality on both fronts, you need the currency to be like a coin — a cash type transaction. Instantly and cheaply transferable directly from one person to the next, with the help of the P2P network to disincentive double spending.

Lightning network helps with some of this, but it can't be considered entirely on par with transacting directly P2P and settling each transaction directly on the Bitcoin network. These will always be two distinct classes of transactions with different security requirements and properties.

A lot of people consider themselves cheated by the developers and the rest of the community, that made the blocks get full on purpose and say the design Satoshi produced doesn't work. That in combination with being banned from places like r/Bitcoin and hit by waves of propaganda has turned people sour. It's not helping, but it's understandable.
