In your example there is only one house, once you sell it you no longer have the house and that applies equally to whoever originally built it as any subsequent purchaser.

The problem is that SMB is not just a filesharing protocol, it provides access to whole heaps of other functionality at least on windows. If all you want to do is file sharing then SMB is a terrible choice.

Requiring a firewall is another poor design decision... You should be able to turn all these services off, but windows makes it extremely difficult to disable the default listening services and the recommendation is to hide them behind a firewall... If the system still runs with the services hidden so that noone can connect to them, then why exactly do they need to be listening at all?

The problem is poor design and inertia... It's not like a simple bug which can be fixed without changing how the software works, there are many design flaws in the protocol itself and fixing them would require incompatible changes. If you're going to drop current windows versions and go to an incompatible system, might as well go straight to linux.

With a VPN login, you can start looking for hosts on the internal network to attack... Chances are on a network of any significant size there will be at least one box which is vulnerable to something, either unpatched vulnerability or weak password.
If you look at an internet facing network, there are generally few exploitable things visible because exposure to the internet ensures that all the low hanging fruit has already been picked, but on an internal network there is all manner of easy stuff. Once you have one machine, you can easily spread from there including using attacks like those described in the article.

Another issue with signed downloads is that older versions with known security holes are still signed, someone malicious can push you the legitimately signed but known vulnerable version, then exploit the vulnerabilities to push malicious code...

There has been shoddy software for years that just doesn't do what it claims, the fact that such software now exists on phones is nothing new.

The POWER architecture has been around longer than X64, the vast majority of linux software comes with source code and compiles fine on power (and arm, mips and anything else) so it doesn't matter what the underlying processor is. A lot of the software that doesn't come with source these days is java based, which will run just fine on power too.

Except for a small number of fairly niche apps, most linux based server loads will work fine on a power system.

If your apartment building is big enough, club together to get a leased line which you can all share... They will install dedicated lines anywhere if your willing to pay the installation costs.

That's where sites like spamdecoy.net come in, use that email address and make up any other information they ask for...

The license database already includes information about what type of fuel a car uses, the same system that recognises license plates can also be configured to flag cars using the wrong fuel, or with an engine over a certain size etc.

That will just cause people to buy/rent a second car for use on the days their existing car isn't permitted...
The registration database includes information as to wether the vehicle uses petrol, diesel or electric etc so it's no harder to enforce.

The problem is that the world is just too complex, that even the few of us who want to understand and make informed decisions cannot be experts on everything...

I always tried to sign my emails with PGP or S/MIME, 99% of recipients have no idea what that is, either in government or commercial circles.

Not so much that its "cool" to share stuff...
Most of the kids share stuff because that's the only way to get hold of it. We used to trade games (on floppies) as kids because we couldn't afford to buy all the games and lending the originals to friends was irritating (floppies get corrupted/lost, etc).
Also cracked copies were often better, as they took out various irritating copy protection schemes, there were many games where i kept both the original disks and a cracked copy because i preferred to play the cracked copy.
