As I mentioned, I switched to Nexo. I have no idea if it is exactly like AAVE behind the scenes though.
I just know I was able to create an account(same hassle as Coinbase or anything else) and immediately deposit a chunk of BTC/ETH/XLM(stellar). I was(am) nervous about how much to trust all of these companies and sites, so I only deposited about 1k in total across those 3 coins. I also did a little experiment which I posted a few pages back where I took a loan out and actually earned more interest with the money I borrowed than I had to pay back! All of it was legit though the % gain on the borrow-invest thing was only about 3.5% so I could make more just trading or investing normally, so after a week I paid it back.
You can do what you want, and I enjoy reading your opinions on the topic and I'm happy to do any follow-up reading you offer, but I'm gonna hold my ground on the fact that this entire space is not as simple as you believe it is for the common person. I consider myself technically adept to a reasonable level and I struggled a bit. No way common people will understand how to get in this space at the level you talk about.
Now I do think people can understand the coinbase(not pro) and even paypal lets you buy crypto now(do you really own it?). That is how the door opens for others, name brands, marketing, simplicity.
Soooooo.....on to the entire ETH debate. I don't see many arguing that the system itself isn't powerful or doesn't have potential, but if people can't figure out how to brand it, so to speak, it's going to be a long slow road.
