Are deference games a thing?

Everyone starts off with a voting card. People can give away their cards. At the end, people cast votes using the cards they have, so people with lots of cards get lots of votes. (If you don’t like what your card is being used for, you always have the right to take it back.)

Maybe this could be used to implement something more like direct democracy? Have lots of votes every day instead of just one every four years. Most people don’t vote on most issues, instead they give their card to their wisest friend who gives it to their wisest friend who has hundreds of cards and spends some free time each day thinking about what to vote on. Other people (e.g. Oprah, Elon Musk) would have millions of cards and would have staffs of advisors telling them how to vote. They’d basically be like congresspeople.

Surely there’s a literature on this idea. What terms should I search for?

Also: Is it a good idea? How would it be worse than the current system?
