Practically speaking, 99% of advertising is covered by a dozen or two primary channels which are obnoxious and ubiquitous. The goal should be to regulate platform-ads, e.g. print, billboards, TV, radio, web, streaming, social media. Ads are all already clearly regulated within the limits of freedom of speech, such as criminalizing false advertising, as another comment has pointed out. These platforms are also generally regulated for obscenity, harassment, etc., which if anything are much more subjective than commercial activity.
> What if I hire a large staff to go out and sing the praises of my company? Walking downtown shouting to the rooftops. That is not advertising, right?
That is (or should be) prevented by laws against disturbing the peace or similar. Which is more along the lines of reasonable solutions in general. Banning advertising wholesale seems impossible, yes, but regulating the actual most common mechanisms of selling ad spots is much easier.
> Ok, now suppose some strapping young individual creates a service that pays websites to carve out a little div on their site that will display these employees songs of love? This strapping young individual now sells this service to companies wishing to more easily get the word out to more people. Is this advertising? But I am not paying someone to make the ad, my employees are doing that.
You're paying somebody for the distribution of the ad embedded within/alongside content (websites) you don't own.
> How is this different than my company posting on facebook? Where is the line?
Posting on Facebook is clearly distinct from paying Facebook to promote your ads.
