The Inevitable Issue with amiibo

A recent YouTube video by Arlo has sparked a bit of conversation about amiibo. Nintendo's little figures are quite the collector's item due to their popularity. The high detail of the figures and the features they unlock make it hard to resist the temptation to collect them, but now they've spiraled into a nightmare that Nintendo hasn't stopped.
Amiibo are very rare. And that's for two reasons:

1. Stores aren't selling enough. If you go to your local Walmart, you might see a couple of Daisy and Waluigi amiibo. My local Walmart hasn't stocked new amiibo in several months, and they just seem to be waiting for the current ones they have to sell. They have three amiibo in stock, and I wonder what they would do if someone bought them all.

2. Nintendo doesn't make enough of the ones people actually want. Link and Mario, despite having several different versions, don't have any versions that are readily available on Amazon. They exist, but they're insanely highly priced. The only amiibo that you can find easily are the Animal Crossing figures.

But why would Nintendo not just make more Mario amiibo? Clearly people want it and it's not like Nintendo is making any money from the people selling them for insane prices! Well at this point it might be because there are several different types of Mario amiibo. There are two 8-bit Mario amiibo, two Mario series amiibo, and one Smash Bros series Mario amiibo. At this point the question is which version of the Mario amiibo should Nintendo restock.

And that's the inevitable problem that Nintendo was going to face. There are too many amiibo figures available. Physical products are a pain to make because they take up room and they take time to produce.

And these issues with amiibo end up creating a pattern. Because amiibo unlock various features in games, and people want those features, amiibo become harder to find because more people want them, which attracts scalpers, which creates a downward spiral into becoming hard to find expensive DLC.

The best solution is for Nintendo to create an amiibo bank, where you can store all your owned amiibo and let you select which amiibo you want to use. They can also sell amiibo digitally through the Switch for you to add to your amiibo bank. Will it happen? Probably not. I'm not even convinced Nintendo knows it's a problem. The way they've been adding copious amounts of amiibo features int their games makes me think they're ignoring that the issue exists.
