Bonjour Ann !
Here it depends of what you're trying to say.
When you say J'aime l'argent, it means I love money, speaking about money in general, hence the definite article.
But when you say J'aimerais de l'argent, it means I'd like [some] money, and you're referring to a (vague) quantity of money, which is a bit more specific.
If you said J'aime de l'argent, it'd mean I love some money, which sounds weird, as it restricts your liking to a portion of the thing. Usually, when you express a liking, it's not partial, hence the use of definite articles most of the time with aimer.
But with aimer in Le Conditionnel, it's more something you would like to have or do, hence the possibility of introducing quantifiers.

I hope that's helpful!
Bonne journée !
