Then it isn't needed.

I would write that:
"You can pretend there isn't a conflict, but there is one."
Economists don't say this, what they say is a small amount of predictable inflation is better than deflation.
They do say it, and the reason they say it is that "wages are sticky" -- that is, they tend not to drop even when the market-clearing wage drops. Since it's very hard to reduce wages in nominal terms, inflation helps allow labor prices to drop in real terms.
>"Seriously, make symbols for humans that are easy for humans to tell apart: lI|"
At least when I hand-write, I usually print (not cursive) yet I always use a cursive lowercase "L" when it is a code (like in a user ID or variable name). And capital "I"'s I always put top/bottom strokes. Pipes I write as two vertical hyphens (with a space in the middle). Oh, and slashes through zeros.
>"Now tell me your take on the Oxford comma"
I was taught in school (USA) that commas are important, lists should have commas, and there should be a comma for each element in the list (even before an "and"). I have written that way my whole life, I think it is clearer and more logical, and I am not going to stop doing it.
Related on reusing coax cables...
The original builders of our house had coax in every room (I guess they wanted to watch TV a lot). No Ethernet. Fiber comes to house technical room, but from that point onwards no network cabling. Would have been a pain to deploy a new set of fiber or CAT6/7 cable everywhere, so mostly surviving with Wifi. However, for "trunk" connectivity I got a couple of these:

I'm just using them for point-to-multipoint connectivity - had to get a new splitter. I got one next to my router where the fiber comes in and I get a pretty sweet throughput. Even though the bandwidth is "shared", it's actually close to 3 Gbps total across all endpoints. For point-to-point you get 2.5 Gbps because the Ethernet port only supports that.
