Exactly. There was a netflix series a few years back called Maniac where characters could choose to listen to in-person sales pitches if they're unable to afford bus fare, for example. Such a scheme would not work because if you're too poor to avoid bus fare then you're too poor to be likely to purchase an advertised product. Analogously & conversely, if you're willing to loosen your purse strings for paid content then you're also likely to have disposable income to pay for advertised products. This is why Facebook will never offer a paid ad-free service; it would remove all the actually valuable advertising targets from their pool of users.
