I think that is too much, but it should be almost entirely banned, with only very limited exceptions. Advertisements which you are specificailly looking for, such as catalogs for those specific things, could be one of those exceptions.
However, even regardless of these exceptions, there will need to be limits, such as: do not be dishonest, do not emit light, do not waste power, do not spy on you, do not block the view of other things, do not try to prevent you from seeing them, they cannot pay you or give you discounts for seeing the ads, etc.

I think it will need to be a "nearly banned" ground rather than the "middle" ground, though.
> Ad companies need to be reined in. They cannot control themselves.
This part I agree with.

But, this part, I think that won't work. Even if it does work (which it won't), it is bad for freedom of speech and freedom of opinion.
