Absolutely, yes

Are hollow points worth the extra cost in large numbers?
I don't know a whole lot about handguns, so bear with me here. I understand that, bullet for bullet, a hollow point is going to be more effective than FMJ. In small numbers hollow points make more sense, but in large numbers there's an issue of cost. So let's say I'm stockpiling ammo for an invasion of hippies, zombies, hippie zombies, zombie hippies, or something of that nature. In that case, would I be better off having more rounds of less deadly FMJ, or less rounds of more deadly hollow points? And if the caliber is a factor, let's say 9mm, but I'm curious in general.
Hoss, welcome to the forum and welcome to handguns (I expect you are contemplating getting one soon, hence your question.)
It appears your question is focused solely on social shooting (people to people), so I will ignore the relative merits of expanding bullets vs solids on thin-skinned vs thick-skinned game.
One quote I cannot reference, but fully believe is, "More men have been killed with the 9mm than any other handgun round." Probably true because there have been more 9mm handgun rounds fired (mostly in wartime, but also in police work) world-wide than any other. And these have been mostly full-metal jacket.
So, why choose hollowpoints?
In a civilian shooting situation, your goal is not to kill, but to make the perpetrator of an act, stop that act. Hollowpoints are more effective at that, and less lethal, as a bonus.
To make a man stop doing whatever it is that made shooting him justified, it may take multiple hits from a round that (again, a quote I cannot reference, sorry) "a 9mm, round nose slug will pass through tissue with with little tissue damage and very little bleeding, thus, often it will take multiple hits to show any effect." On the other hand, an expanding bullet will produce a great deal of immediate effect.
So, a single hit with a HP (or ther expanding bullet) is likely to produce the desired effect where multiple hits with FMJ are required to produce the same effect.
Then there is the lethality effect. Multiple hits with FMJ are more likely to be lethal (although time-delayed) than a single hit with a hollowpoint, provided medical attention is timely.
This is why police departments use hollowpoints. More effective AND less lethal.
Here's my recipe. Practice with cheap ammo (cast lead solids, round nose fully plated or jacketed bullets) that performs similarly to the ammo I choose for actual defense. Fire the "real" ammo enough to keep my familiarization current and to rotate my stock (replacing old ammo with new), and fire lots and lots of "practice" ammo.
The cost of ammo is not so great (when compared to the cost of a gun, practice, training & education, etc.) that I would use less effective ammo when my life is on the line. Very likely, if you actually shoot someone out of necessity, the cost of all the hollowpoints you have ever fired will be the least costly element of the whole experience. I fire about 25 rounds of "practice" ammo for every one of "real" ammo.
So, to sum up.
I choose hollowpoints because they are less lethal than solids, for their effectiveness. I choose hollowpoints because they are more effective than anything else. I disregard the cost of hollowpoints because one or two dollars apiece is cheap, compared to life.
Caveat: Not everyone believes HP produces more effective stopping power than FMJ. Not everyone agrees that HPs are less lethal. So, expect argument in this forum on those points. I don't believe either question has be settled completely, but it has been settled in my mind, though I am open to new information.
On another point. It is often said that a particular round has "knock-down power". Yes, a big slug at 1300 fps can knock over a steel ram or a send a bowling pin flying off a table, but no handgun slug can knock a 200 lb person off their feet. The physics just are not there. When you see a person fly up in the air from being hit by a bullet (or even a shotgun blast) it is a massive muscle flinch caused by the shock reaction of being hit. In the movies they do it with cables and a harness.
