Good analysis. I remember about 20 yrs ago when I first started ebay. I knew it was a game changer. I remember putting quite a bit of savings into it, as such. It worked out fairly well back then. Just pick the right cards and don't sell short. And then try to time the stock market.

I think COMC's rise over the past 10 years, in particular, is a strong point for the health of the hobby (in general). The site's foundation is in buying and selling of lower valued cards and in set builders, and the company has grown tremendously. It's now one of the bigger sellers on eBay and elsewhere, I believe.
And here's a hair-brained theory on the state of the hobby, in general, and recent price increases...
Access to the hobby has increased dramatically over the past 10-20 years. eBay is now readily available on most everyone's phone, major auction houses offer numerous auctions every year and people can participate from anywhere in the world, and collectors have the ability to purchase and learn about the hobby at a level that is unprecedented. So, in terms of the demand side, it is easier than ever for a seller to access a greater population of the people who want a card. With the greater access to the demand side, prices have gone up - but perhaps this isn't a bubble for prices, perhaps this is actually more of an accurate representation of true price when it comes to supply and demand.
In this way, despite some high profile scams recently (forged T206s, trimmed cards in high-graded slabs, shilling, etc.), perhaps the state of the hobby is actually as healthy as ever.
