Getting used to things being easy only becomes a problem when you can't deal when they're not.
But too many people cant deal with things when they are not easy.
Go try to live in the wilderness for a month, without supplies, cut off from all human contact.
Can't survive? Lazy.
You do realize that you're carrying this to an absurd extreme, whereas the previous statement -- that some people can't deal with things when they're harder than normal -- is actually a valid complaint? The difference between the two statements is like comparing getting used to swimming in a cold pool to adjusting to swimming in a freezing ocean.
Getting used to things being easy only becomes a problem when you can't deal when they're not.
Which is best dealt with by making sure they don't become hard again.
Yes, that's the best way to deal with that, but if that's been your modus operandi for dealing with troubles, welcome to reality! Here you, quite frankly, have next to no say in the events going on around you. You quite often can't avoid things becoming hard again, whether it's a mild case or extreme case.
In short, you're using blanket statements and exaggerations to support your point, which, I might add, has deviated quite a lot from the original argument of whether or not using a machine to remove fat is a supportable project. The programming analogy fails to really counter DarkWolf's complaint, somewhat general and a tad off-topic as it may have been.
And then a bonus chunk of text, as I am fairly certain you'll disagree about the applicability of your analogy:
Ultimately, while you do need to create the universe before you can make an apple pie from scratch, no one actually cares if you make it from scratch or not just so long as it tastes good. You don't need knowledge or experience in the boring parts of life if they're skippable.
That doesn't consider the times when the universe goes 'oh, hey, you were planning on <insert action here>? NOPE.' and forces you to act outside of your zone of convenience. A large chunk of the statement that 'some people have trouble coping with difficulties' applies to circumstance that are not self-imposed.
