Isn't your routing number or IP address already protected? What would be the use in a VPN? Virtual network. It is for those who don't want to buy a modem or a router. Just invest in one, and you've pretty much protected your computer.

You still need a modem/router if you use a VPN or not.
VPN is used mainly for privacy. If you use your default IP address, big brother and his marketing buddies know everything you're doing. Using a VPN helps to obfuscate your activity by encrypting and tunneling your connection to different exit points around the globe.
Some also use a VPN to appear to be coming from another country so they can get access to different content on NetFlix, etc.
I mean, you left the important part off of that: PRIVATE. Without a Virtual PRIVATE Network, I could sit outside your house, get on your wifi, and packet sniff your traffic and see everything you're doing. And this is just the tip of what I could get access to.
With a VPN? I'd see you "tunneling to Germany" and that is all. (Not even sure I'd see your destination).

No.
Threats and protections are not all the same. Just as seat-belts, air-bags, crumple zones, etc. are all protections for a driver, but they do different things. Thus, saying "all you need are seat-belts" is just as false as "just invest in a modem/router and you'll be protected". The key is - protected from what?
VPN's technically provide data confidentiality. Anything passing across that VPN is encrypted between you and the VPN provider. So anyone sniffing or intercepting that traffic won't be able to decipher anything (in theory).
IP addresses identify a host. While that information can lead someone to you - by itself, it does't really verify that it was really you that was using the device. Like a phone number, it can be traced back to you as the owner... but there has to be other factors to validate that you were actually the one that was communicating. Of course, that is still a "lead". So using a VPN can remove that factor as well as you are now communicating through a proxy.
All of these "controls" also only work if used properly. There was a student that sent in a bomb threat (MIT?) to avoid class a number of years ago. He tried to hid behind TOR ... but wasn't smart enough to realize that this only worked from the outside. He used the University's network to access TOR.... of course, everything he did on the university network was traceable....
