Now you can still heavily promote the ETF to retail and still earn a cut of the management fee, which is great. But importantly you are two steps removed from the investment decisions (one because are not running the ETF, two because you are not directly picking the stocks)

That frees you up to do whatever trades you like in your personal account. For example, say you wake up one day and decide you really like $NOK so you buy some for your personal account. Obviously you use your youtube/twitter/tik tok/whatever to tell your audience about

this awesome new stock you are getting into, then they go and talk about it on reddit/twitter/youtube/whatever and promote it to their day trader buddies, friends, family etc. Your excitement about the stock creates a big online "buzz" about it

which is exacerbated when journalists with a desperate need for content pick up on the story, promoting it to an even wider audience. Eventually it becomes one of the top 75 most talked about stocks online,

which is picked up by the entirely objective, quantitative methodology of your ETF, which follows you into the position, pushing the stock price up further and creating a nice exit opportunity for you. Rinse and repeat.

Obviously for this to work the ETF needs to be rebalanced frequently (e.g. monthly) and you need to focus your attention on stocks that are not already in the ETF but are close. You'd need to be particularly active 1-2 weeks before the rebalance when you can have the most impact.
