The reason you see this 'restriction' is due to the fact that Stack Exchange employs some 'trust' requirements before you can go unilaterally editing other person's questions/answers, regardless of intent. One of those requirements is a peer-review on all edits up to a certain point, and another is the requirement that edits be 'substantial' (6+ characters) before you submit them. These help filter out users who come here just to edit things without participating in the question and answer.

Is this helpful to prevent bad/spam/nefarious edits? I don't have that data, I won't speculate, and it's beyond the scope of this question. What I can say is that this will not be changing any time soon, and we really don't have any control over it as a community.

What we can talk about in this question is that it's not documented well, but once you reach the 2000 reputation milestone of 'Edit Questions and Answers' you lose both of those restrictions. You can create edits that are as big or small as your see fit, and you can apply them immediately. This is a lot of power, and with power comes responsibility. This effectively allows you to unilaterally change a question, and as such, possibly the askers intent. That's a big responsibility. It's not to be taken lightly.

I would like to speculate, with a high degree of certainty, that one of the reasons for these restrictions is to force new users to get used to what the community expects out of edits. After all, we are all expected to get along with each other and work together towards a common goal.

At 200 reputation points a day (for the daily cap) that means you only need 10 days of rep-capping / mortar-boarding to reach that milestone. That's not a significant amount of work, and it comes with other rewards.

You may have also noticed (as I see you have a tag-wiki edit) that you get a +2 reputation boost for each and every edit that you suggest before meeting the 2000 reputation requirement that passes peer review. This has a limit, I don't recall what it is (if anyone finds it feel free to edit this answer to include it) but you can get a fair amount of rep from edits alone. Between that and answering (as I see you have a good answer already posted on this community) you will reach that limit in no time.

So, the best I can suggest to you, keep editing, keep asking, keep answering. You'll get to that 2000 reputation requirement eventually, and I would like to hope that you are able to make great improvements to our questions and help the community out. After all, we're self-driven and self-governing (for the most part, mods are there to help guide us along the right path but we make decisions as a community), so all user input is welcome. :)
