1 - Attempts to side-step the law (however misguided the law is) -> Most are attempting to side-step credit card service fees while remaining open to transact across the world in real-time. Most popular CC's fail at the real-time part and cause unnecessary resource usage, but hopefully that will change. Actually, most CC's fail at trying to side-step the law given all transactions and account balances are public for most coins. You could say tax-avoiders prefer money they can hide through sketchy banks or cash rather than CC.

2 - Trivial to do using a typical centralized database (e.g. Federal Reserve or VISA) -> Bitcoin, Ethereum and others can do Smart Contracts which means delayed sending, multi-sender transactions that serve as escrow and in the case of Ethereum programmable using it's own language to do any number of actions/apps. The important feature is that this is handled by the network using your own transaction, you don't have to set up the escrow through a company like VISA, Paypal, etc.

3- Tantamount to waiting for a greater fool to buy out the current players -> This is true of all CC because it's an open, yet small market. The earlier you get in, the better your outcome. However, it's not like CC's NEED to explode in price to be useful, competitive or solve a real-world problem. Getting rich is a secondary effect of having a functional CC reach adoption. Look at MemeCoins like Doge and Banano to see adoption is easier when everyone abandons the idea of getting rich off a coin.
