Meh, universal healthcare for PC's can easily be avoided by denying maintenance until they die and a new crop is purchased. At least at scale. For any individual user the friction of switching hardware may still incentivize some minimal checkups, i.e., keep windows update & defender services running and let them reboot the system no more than once every two two months.
Figure the local router port-forwarding will protect against the most obvious threats and otherwise hope your personal BS filter doesn't trojan in some ransomware. If it does & it's a person pc then wipe (more likely buy) a new machine, lose some stuff, and move on. If it's a corporate pc, CYA & get your resume together.
As my own CYA: These are not my own recommended best practices and I don't advocate them to anyone else as either computer, legal, or financial advice.
