You can't 'pull the SSD out at snap it into a new one'.
It just doesn't work that way. You can't strip away a flash memory from a logic board and stuff it on a new one.
You should do your research before asking a question like this on the forum...
What?! Really? Apparently, you are the one who needs to grab yourself by the collar before answering questions you think you have the answer to.
That's EXACTLY how it works. Modular units are built to "strip away" and "stuff it" on another.
And for future references; if you want to check rather certain parts of an apple product is replaceable/interchangeable or not - tear downs and repair guides of ifixit.com is the way to go.
And when I said that the SSD was smoldered in - it was in a metaphorical sense that it's pretty much impractical to replace.
I did mention in my previous response that it is possible pull them out and shove them back in - although i see very little reasons to do so.
At least for the purpose of the question, the given option cannot be viable as his/her solution.
Sure, iFixit is a great way to look up this, but have you ever considered that everyone might not know about the site? The TS for example?
it so happens that the SSD is for one, the only part of HD/CPU/RAM/Etc that is replaceable. And it also is extremely easy. It's attached with ONE screw. One.
Why would you give a nonsense statement like that, with contradicting information, when the person asking obviously is doing so since he/she doesn't know. And then claiming it was metaphorical, when you yourself said that the person probably doesn't know how to take a computer apart. You are first claiming a level of (low) intelligence/knowledge of a person, which is very offensive I think. And then making statements "above" that made up level of knowledge, which then turns out to be factually wrong.
What a load of @#%.
Also, to appeal to the TS to not "ask for a second opinion" must be against some fundamental rule of this forum or forums in general. If not presented with seemingly reliable and researched facts (unlike yours) to weigh opinions and facts against each other is how you reach your own decision in the matter.

I wanted to get a cheap 11" MBA as a way to save a duplicate of my images when going on a long trip later this year and myself researched the possibility of putting a larger ssd in place of the 64gb standard one. I found lots of contradicting information on module sizes, connector standards and so on. - I think the question asked in this thread to begin with is completely legitimate therefore.
