Indeed, only the memory card launch problem should be a issue, but after all we are many in here that have launched and managed to find it again, way more then the people that have launched a memory card and never found it again.
It is a good idea to be careful inserting or ejecting ones memory card in the camera.
My last launch was a evening after sunset last summer, and it was a brand new 256GB card, i was not able to find it with the light of my phone, so i climbed the stairs to my apartment and got my "instant daylight" flashlight, and using that i found the memory card ( under front passenger seat where i already looked ) in a minute.
Another + of a good card readers also is you can play videos from it with no issue, using the camera as card reader or a old POS card reader you most often cant do that and get lagging playback.
I can play 4K / 60 FPS 100 mbit footage from my action cameras memory card in the card reader with no problems, this is nice as you can browse the footage on the card without having to copy it to the computer first, not least if it is only some of the footage you need.
But like i said if you have meat cleaver hands and 10 thumbs, putting a piece of tape on the memory card ( thin tape ) is a good idea.
I still dont do it myself, but it is a good idea none the less.
Here demonstrated on a CF card, which are a lot larger, but the principle are the same.
