It's just as easy? When you have a monorepo with 5 million lines of code, you're only going to focus on the part of the code you care about and forget the rest. Same with 50 repos of 100,000 loc.

Enforcing standards means actually having org level mandates around acceptable development standards, and it's enforced using tools. Those tools should be just as easily run on one monorepo than 50+ distributed repositories, nay?

Even in the best case of what you are describing, how are these tools configured and their configuration maintained except via PRs to the repos in question? For every such change, N PRs having to be proposed, reviewed and merged. And all this without considering the common need (in a healthy project at least) to make cross-cutting changes with similar friction around landing a change across repos.

If you wanted to, sure, applying enough time and money could make it work. I like to think that those resources might be better spent, though.
