I'd argue the consent is you clicking on the video to watch it. Sponsor spots are the norm, especially for large well-known channels.
The fee is charged to users if I understand it correctly? So essentially YouTube premium? That can work, but not everyone can afford to spend money on a subscription and if you block access to the platform it's arguably you will be able to grow to the size and diversity YouTube has. Floatplane is an alternative where you can directly subscribe to creators but that's not cheap if you watch a wide variety.
