I think it's interesting to standardize these things as ERC20 tokens. It's still very early days, but that allows you to leverage the entire ETH econsystem which is still growing. For example, I could store those ERC20 tokens on my hardware wallet, or phone wallet, send them to others without using a platform's website, etc.

Also, your comment reminds me somewhat of the infamous Hacker News comment when Dropbox posted ("everything you want to do can be done simply with rsync"). Sure, perhaps it's simple for tech folks that know how to build a database and a website that lets you mint and share tokens. But what if you are a popular Youtube vlogger? You either don't know how to do that, don't have time to, or don't want to spend the money. But perhaps you'd use this service, quickly mint tokens, give them away to users, and invent interesting use cases for them.

Personally, I love this idea and think it has great potential. Will anything useful come of it? Who knows -- it's early days. I think the most interesting use cases, if they exist, haven't been thought of yet. I look forward to seeing what people do with it.
