By not using the internet.

Back in the day when people wanted to share something with the world they would set up a website (instead of sharing on social media, because there were no social media). When large files needed to be moved between people, Bittorrent was used (instead of CDNs, because there were no CDNs).

These still work and needs to be rediscovered and used. Perfection is reached when torrent downloads are integrated into the browser itself.
