Would limiting Politics, NSFW, NSFL and downvotes content to users with only 500+ comment karma be good?

One of the biggest problem I have seen on almost all alternatives including the new ones is that they all become dominated with political content. Would the following ideas be appreciated by users?

All posts and comments must be marked with a flair if they are:

Only users with certain amount of post karma and comment karma will be permitted to post such content. Let's say 500 post karma and 500 comment karma.

By default, such content will also be hidden from users who are not signed in as well as all users unless they enable such content in their settings.

Posts will only have upvotes and no downvotes. Comments will have both upvotes and downvotes but ability to downvote will be restricted to accounts with minimum 500 post and 500 comment karma.

A comment can be downvoted but only up to -4 will count towards the user in order to prevent hive mind.

Downvote will also result in -2 points on the person downvoting too.

Moderation will be done by users who have 500 post karma and 500 comment karma. Such moderation logs will be public. This moderation will involve ability to change the above flairs (nsfw, nsfl, political etc) on posts which are not correctly flaired.

What do you all think of these ideas? Are some of them good or bad or can be improved?

Note that some of the ideas are my own while others I have learnt from other sites like hacker news and lobsters.
