If everything was a neat tidy standardized set of TLDs, the PSL wouldn't exist.
But it isn't. PSL allows computers to understand political, social, financial, and arbitrary decisions that have an impact on security.
For example, uk.com has no legitimate right to be a TLD. But someone managed to get enough other people to buy subdomains that we have to treat it as such. If we refuse to do so, it harms end users and not uk.com.
