@cjd the hurdle for a new entry is exasperated by the voluminous and likely draconian regulations of each municipality, county, and State, plus the thousand of fed agencies' standards that violations can cause stiff fines, plus the actual fed laws... who has the staying power to build a new competitive regional or coast-to-coast or global-regional or full global network? Amazon is launching its own thousands of tiny mini-satellites to create a network. There may be some others.

@Dassinger
The aim of PKT is to split the role of "ISP" (billing, customer service, routing packets, jockying for IPv4 addrs) from the role of infrastructure operator - the actual operation of physical equipment.

Point an antenna, run a fiber and Virtual ISPs around the world purchase Bandwidth Leases on your infrastructure and use it to route traffic for their customers. Your router has a crypto wallet and coins show up when bandwidth leases are bought, all you have to do is keep it working.

@Dassinger
Virtual ISP should be the one in charge of dealing with any applicable regulations.

It should go without saying that monopoly power grows from control over infrastructure, hence the goal of millions of small infrastructure owners, and each network connection sub-dividable into hundreds of pieces.

@cjd ... Point an antenna, run a fiber and Virtual ISPs around the world purchase Bandwidth Leases on your infrastructure and use it to route traffic for their customers. <-- that, in my view, lends toward a natural near-monopoly; few players having the dominant share of or virtually all of, or all of that market. More players can potentially offer more choices, and equal or perhaps premium service - splitting the traffic more and more would leave less of the sum to those larger cos.FreeMkt.
@Dassinger
You mean monopoly of one or a couple of Virtual ISPs (like GAFA) ?
@cjd in the case where there is insufficient perceived profit opportunities, new or niche co.s can serve a tremendous value to get good service to those who would remain unserved or underserved (and possibly also, charged more highly, for any service. ... where the market is well fleshed out, provided for, there the opportunity (not a guarantee) ought to still be avail. ) An common carrier wholesale pricing may be avail. for passage though the already developed areas, on their bandwidth, equip.
