This is an important topic in understanding how money actua…

I'm not sure that equation completely holds water. Plenty of counterexamples where P and Q are not ever going to be inversely proportional.

Look at the role of V.

That, and recognize that these are aggregates, and must be broken into their component parts to properly understand it.

The role of V becomes irrelevant after it reaches a certain level, thus also rendering that equation less relevant. V is essentially a synonym for liquidity.

No...

Liquidity is a very different concept than velocity.

Tell me, what happens to prices when liquidity changes? What happens when velocity changes?

Velocity implies liquidity. And liquidity implies velocity. We have a logical equivalence.

Liquidity does not imply velocity. Volume does. I think you're conflating multiple different concepts here.

Liquidity implies Volume which implies velocity. By transitive property, Liquidity implies velocity. If a->b->c then a->c.

Liquidity does not imply volume.

Trying to use logic on concepts you are misapplying is a recipe for failure.

Then you can point out a counter example where liquidity was high but transaction volume was low? I've never seen that.

Price doesn't change. People use different money that isn't as broken.

Logic is useful for idiot checking your theories. If you find logical equivalences, you probably should not form theories that suggest different outcomes for the equivalent variables.

That's because most people conflate volume with liquidity...

That response makes me unlikely to continue this thread. I am not interested in wasting my time with nonsense.

You must start with sound premises for a valid argument to be of further use.

I'm not being a smart ass. You're thinking strictly in USD, which I think is limiting. But when BTC effective liquidity decreased dramatically, I used LTC bypassing the liquidity issue and bought my goods (BCH). Keynesian economics are weak.

Now you're telling me how I think, and implying I'm a Keynesian?

And you continue to misapply the concepts.

I'm done wasting my time and energy. Bye.

No it's very possible to acquire an eclectic understanding of economics. But that equation is Keynesian and I was just pointing out it's not particularly strong in the context of multiple readily available currencies. No offense intended.
