ELI5:What is the purpose on limiting the amount of stock trades you can make if you do not have $25000?

That rule only applies to pattern day traders. The reason is that the SEC thinks that people with more than $25,000 in their brokerage account are experienced traders who know the risks and can absorb the losses. 

The rule is enforced by the brokerage, and they tend to err on the side of caution. The rule is only supposed to apply to margin account, but they sometimes apply it to cash accounts as well. 

Again, this is only for day trades, buying and selling a stock in the same day. There is no limit to the number of stocks you can buy or sell on a given day, so long as they weren't purchased and sold on the same day.
