I think this transition is a slow step towards phasing away from the mint in box collectors. I know that's a hard pill to swallow for many. But simply put, I imagine Hasbo has determined they're statistically a small enough part of the market that they can either be partially converted or lost from revenue.
Back in the day, in the old Warrior Forum when everyone was on the EZboard system, in the military 1/6th side of the hobby, there were some posts about lobbying the brands to just use plain white mailer boxes and remove all art work and most of the packaging, sans what was needed to keep the items safe in shipping.
Ron Volstad, who did artwork for Dragon Models, came in hot and heavy. He was unrelenting. Basically saying we were all lobbying to take food off his table.
I see his position. And I don't at the same time. I had nothing against Volstad, but he just plain held the line, didn't want to see the other position, and I recognize it must be incredibly difficult to make a full time living as an "artist" I also understand, and this might or might not be controversial here, that artists in our hobby, the well known ones, are generally going to be high maintenance personality types. Everyone? No, certainly not. But the "quirks" are clearly there if you watch long enough.
While the scale of Hasbro is certainly different, a heavy change in how figures are released in their packaging could end up costing some people their jobs. Hard to say, maybe or maybe not depending on the situation.
Given all that, I'd say still do it. You are right and I agree with you, all this wasteful packaging is not good for us in any sense. Cost wise, health wise, environment wise, etc, etc.
What do I think will happen? At some point, we will turn into a cashless society. It's inevitable. It's a system designed to make people easier to control and punish. Once we transition into a cashless society, I believe you'll see fewer brick and mortar stores available and as fewer and fewer big juggernaut corporations take over, they won't need to market their products. If only one company makes all the food in the country, why do you need box art? Or lots of advertising? It's not like there are going to be 9 different companies making oatmeal. There's just gonna be one kind of oatmeal for everyone in a plain marked box. Probably industrial bulk sized as well.
The traditional widespread brick and mortar dedicated "toy store", as some of us old enough to remember it, is now dead. Other types of businesses will follow suit.
So I think packaging will go in a direction more in line with your vision of it and hopes for it, but it will be a lagging indicator of some pretty huge new and lethal problems for us in tow.
But until we are being wiped out by Sky Net, I do think gradual changes are more likely to happen. Or are better suited for a transition. Going to never seeing a figure at all on the shelf immediately is just a rough jarring change for consumers. Some will say, and you might say, we don't have time for a gradual change. And in that, I actually would agree with you. But if the change is too abrupt, nothing will sell, and then people lose their jobs.
I want what you want. It's just there's layers of context inbetween. What's good for people and how they typically behave as consumers rarely lines up. Not to be grim , but I'm pretty sure we are at the end anyway. But for the sake of my nephew, I hope I'm wrong.
