It's important to remember that the service Bitcoin miners are providing
us is *not* transaction validation, but rather decentralization.
Validation is something every full node does already; there's no
shortage of it. What's tricky is designing a Bitcoin protocol that
creates the appropriate incentives for mining to remain decentralized,
so we get good value for the large amount of money being sent to miners.

I've often likened this task to building a robot to go to the grocery
store to buy milk for you. If that robot doesn't have a nose, before
long store owners are going to realise it can't tell the difference
between unspoilt and spoilt milk, and you're going to get ripped off
paying for a bunch of spoiled milk.

Designing a Bitcoin protocol where we expect "competition" to result in
smaller miners in more geographically decentralized places to get
outcompeted by larger miners who are more geographically centralized
gets us bad value for our money. Sure it's "self-correcting", but not in
a way that we want.

Note how that VPN, and likely VPS it's connected too, immediately adds
another one or two points of failure to the whole system. Not only does
this decrease reliability, it also decreases security by making attacks
significantly easier - VPS security is orders of magnitude worse than
the security of physical hardware.
