The community guidelines ensure the well-being of the community. if they were removed, people would be mean to each other everywhere, it would be chaos, etc. There are rules that you'll have to respect throughout your entire life and you have to deal with it. It's like the law. If there was no law, it would be chaos.
I don't see why the community guidelines should be removed, you just need to respect them and it really isn't that hard to be nice, constructive, honest, etc. If you think you can't go a day without being respectful or unfriendly, then this site probably isn't for you.

Is there a particular reason why you want them to be removed? Generally when you post a suggestion, you're supposed to explain why you want your suggestion to happen. Blockspamming and emoji-spamming is not a good way to get your point across.

The only reason I can see why you made this suggestion is that you want to be able to go against the Community Guidelines and get away with it. Is this truly what you want — the ability to act disrespectful, unconstructive, and dishonest to people on a children's website?

Sorry, no. The Community Guidelines are necessary to make sure that Scratch remains a welcoming place where Scratchers can learn and share.
