Remember the Internet was devised initially (DARPANET) as a weapons 
grade military network that could withstand a nuclear attack and still 
allow someone to push the red button.
Which is why IP packets have no field representing 'cost' embedded in them

Imagine if any website could charge you for access seamlessly, with your 
ISP charging you the picocents for each packet downloaded via them and 
reimbursing the sites owners.

NO advertising needed

But the point remains TCP/IP was optimised cor reliability diverse 
routing and connectivity.
Any security was to be provided either at a physical level - cables 
inside locked locations - or at a higher level by firewalls, encryption 
and network virtualisation.

It is not the fault of the Internet that people do not routinely employ 
these to protect their networks.
