This is unfortunately true in the capitalistic system we're currently living in. We're constantly being presented with new goods and services that we "need," portraying them as a must-have, nudging us to purchase more and more stuff we ultimately don't need. It creates a vicious cycle of unsatisfaction and excessive spending, as these items satisfy us for a brief amount of time, which then leads us to purchase newer stuff to saturate our appetite.
To be fair we do not "need" them, but by logic we can just go find some very cheap land in middle of nowhere, build a cabin, eat simple food from farmers, nothing big, just simple bread and wine and meat all day everyday, with some butter and cheese and eggs and chicken to go with that, and just keep doing that until we die, we won't "need" anything else, maybe some fruits I suppose, and some other food for vitamins. To be fair, the new medical ways are better than old ways in the sense that it could save someone that they used to can't save, which makes more sense, so we would use modern hospitals, but aside from that you could live like it's 15th century and won't have much issues.
The "need" is the need, and if you need it then you need it. Sure you don't need the latest iphone, but you also don't "need" any phone at all, write a letter and send it if you want, but we don't, we use phones. Life isn't about what we need, it's about how we want to live.
