In theory yes, but we’re talking about such a massive dataset that archive themselves would have to seed it forever anyway. But yes, in theory, if there would be a lot of seeders for it, this would be a non-issue, however I highly doubt that there are enough people interested in seeding a petabyte worth of archives. It’s certainly less than people who are willing and able to keep a local copy.

And if you did that with a consumer ISP, they would terminate you as a customer very quickly. At which point you’ll have to pay cloud provider for traffic, or a T1 network for IP transit (alongside colocation fees and actually putting a server in a datacenter and all that).
