They just will never get it. Hell, I think some Bitcoin maximalists will never get it either.

Bitcoin is not being bought by Average Joe to be spent. Period. The non-existent mempool proves this.

It's being bought as a deflationary hedge against the the fiat monetary system, like digital Gold. It's being held. The fact that it can be spent directly with some merchants online is just a bonus (something that can't be done with PMs).

Average Joe is not even spending his hard earned fiat right now (as witnessed by the deflationary environment we are in globally). He's trying to save money for the future. He's probably also desperately trying to pay down debt. So why in the hell would he go through the hassle and fees of buying Bitcoin just to turn around and spent it? A: He isn't and he won't. He's hodling it.
