Has a fix for tags aever been found?

I’ve done a bunch of research both on WP and Google, and so far, I have NOT found where anyone has found a valid fix for line breaks not working! First, why on earth was the functionality of a
tag taken out? There is a reason many of us who know HTML use more than one line break, i.e., I want to place text in a specific paragraph so that it aligns exactly with an image or video. The only way to do that is to place breaks in between my paragraphs so that the text for each image/video will line up exactly as I want it. So far, this has been impossible to do because WP removes all of my
tags and if I switch to visual so that I can actually enter a return, it strips out ALL other HTML formatting that I have done to try to get the paragraph to align with the image or video. This is absolutely asinine! Is there a plug-in that fixes this?
