Here's another thing I consider to explain why I don't bother with components...
Magic has been around a long, long, long time. Long enough that people have figured out how to use it. And if using magic was difficult in some form or fashion, over time people would figure out how to adapt it to make its use easier. Or if they couldn't make its use easier, they wouldn't use it in that fashion.
So if we assume paladins, clerics, eldritch knights and so on exist in the world... it is because people have figured out how to use magic *and* wield weapons without jumping through all manner of hoops. If using magic and weapons *did* involve having to swing a sword then dropping the sword on the ground then casting a spell then reaching down to pick the sword back up... if all of those things were required... NO ONE would do that. In a fight that's suicide. Which means to me that *if* we have paladins and clerics and eldritch knights etc... it's because magic-users have spent the past hundreds and thousands of years figuring out how to use magic WITHOUT having to do something stupid like dropping your weapon on the ground and then turning your back to your opponent to go pick it up again. They would have figured out an easier and safer way to use magic *and* fight with weapons. Which is why classes like paladins, clerics, and eldritch knights are now a thing.
It's like all technology... if you wanted to accomplish something easily, there would always be experimenters out there working with the current technology to expand it and make it cheaper, to figure out how to accomplish it. And over time, it would become easier and easier and easier to do. Which in a lot of ways makes D&D magic kind of dumb when you think about it-- magic has the capabilities to alter the world on the power level of 9th level spells, but because of the game mechanics not wanting to make things too simple for players... things like the "Photocopy" spell only show up in obscure game books in select editions. Something so obvious and which would make wizards' lives so much easier. Something any set of magicians over the centuries who were stuck having to hand write spells into spell books from scrolls and such would have decided long ago that this was stupid and there could be a better way. "Photocopying" spells into spellbooks would have been one of the first ease-of-use magics wizards would have worked on and come up with. But simply due to the game not wanting magic to be too handwavy for players, it just assumes no one has ever "thought of it" or "worked on it" enough to have it be a standard part of the game. Kinda illogical if you ask me.
It's one of those incongruous concepts when you try to pair a typical medieval society with massive magical capability. Not many campaigns and settings ever really take those two things being mushed together into account to produce logical results.
