I think the main catch would be this new ASN would become known by the very companies/services trying to ban non-consumer IP blocks. Providers like DigitalOcean, AWS, and Azure are non-eyeball networks, so you see more bots and geo-shifting users (nonUS users trying to avoid a geo block by Disney for example). Any IP announced by the ASN would be known by looking at the bgp announcement and listed/blocked. Hiding bots and other users among the huge Comcast & Spectrum IP blocks makes it harder for media companies to block them. It’s just how do you legitimately buy a bunch of consumer connections, or get users to install software to share their consumer connection, hence the NordVPN clients I assume.
