Rather than imagining jumping straight into communism directly, let's look at what it would mean to move towards it gradually.

Right now, people have to work in order to provide the basic necessities of life, like food and housing. However, suppose the state provides those things at little or no cost, without changing anything else. The profit motive still exists, and people work for pretty much the same reasons as before. If you want to buy a big TV, video games, a boat, whatever, you have to work for it. Money still exists, and is still valuable, but it's not essential.

Suppose I'm in a relationship I'm unhappy in, but I feel the need to stay together because of rent. If rent is no longer a concern, then I'm now more free to decide who to date based on things other than money. Then, someone who might otherwise be focused on money as a way of attracting a partner, might try to appeal to them in other ways, by showing off physical fitness, creativity and artistic skill, education, etc. Then, perhaps a company appeals to that person by offering a way to develop skills, rather than just money.

To use a fictional example, in Star Trek, everyone's basic material needs are met, but you still have groups like the Ferengi who are focused on profits and money, which is often used for rare goods and collectibles. Many people don't seem to have much use for it. While money still exists, it's not really the same as we think of money today, because the things it's used for are so much more limited.

Of course, we can't just abolish money overnight, but what we can do is work towards a world people are free to act on motives other than making money. And future generations growing up in a world where money isn't essential might look at it in a completely different way than we can even imagine.
