Does buying meat equate to approving of killing an animal? In the Kammapatha sutta AN 3.164(A i 297) a note concerning the meaning of a passage (written by the author of the page dedicated to the sutta it seems) makes me question, the sutta and note are stated as follows :

Endowed with these three things, bhikkhus, as if one was carried off
and put down there, one is in hell. Which three? One destroys life
oneself, one incites others to destroy life, and one approves of
destroying life.{1} Endowed with these three things, bhikkhus, as if
one was carried off and put down there, one is in hell.


Note

one approves of destroying life: purchasing dead animals' flesh, in a context where other reasonable harmless choices are available,
cannot be carried out without approving their killing.

It appears the author of the page establishes a link between approving the killing of an animal with the purchase of meat. I would appreciate understanding more about this link being established.
(As a personal background I had been a vegetarian for around 5 years but due to digestive issues decided to revert to the consumption (and therefore purchase) of meat which seem to be helping a lot).
With mettā.
&quot;Jivaka, I say that there are three instances in which meat should not be eaten: when it is seen, heard, or suspected (that the living being has been specifically slaughtered for oneself)... I say that there are three instances in which meat may be eaten: when it is not heard, or suspected (that living beng has been specifically slaughtered for oneself)...&quot;
Furthermore, the Buddha added: &quot;If anyone slaughters a living being for the Tathagata (i.e. Buddha) or his disciple, he lays up much demerit in five instances... (i) When he says:'Go and fetch that living being'... (ii) When that living being experiences pain and grief on being led along with a neck-halter... (iii) When he says: 'Go and slaughter that living being'... (iv) When that living bieng experiences pain and grief on being slaughter... (v) When he provides the Tathagata or his disciple with food that is not permissible...&quot;


“Killing living beings,
hunting, cutting, binding,
theft, lying, fraud, deceptions,
useless recitations,
associating with the wives of others:
This is a raw stench,
not the eating of meat.
Those people here
who are unrestrained in sensuality,
greedy for flavors,
mixed together with what’s impure, annihilationists,
discordant1 &amp; indomitable:
This is a raw stench,
not the eating of meat.
Those who are rough, pitiless,
eating the flesh off your back,betraying their friends,uncompassionate,
arrogant,
habitually ungenerous,
giving to no one:
This is a raw stench,
not the eating of meat.
Anger, intoxication,
stubbornness, hostility,
deceptiveness, resentment,
boasting, conceit &amp; pride,
befriending those of no integrity:
This is a raw stench,
not the eating of meat.
Those of evil habits,
debt-repudiators, informers,
cheats in trading, counterfeiters,
vile men who do evil things:
This is a raw stench,
not the eating of meat.
Those people here
who are unrestrained toward beings,
taking what’s others’,
intent on injury,
immoral hunters, harsh, disrespectful:
This is a raw stench,
not the eating of meat.
Those who are very greedy,
constantly intent
on hindering and killing;
beings who, after passing away, go to darkness,
fall headfirst into hell:
This is a raw stench,
not the eating of meat.
