Neither love nor happiness are guaranteed. So, in general, the more you experience life and explore all it has to offer, the more likely you will find love and/or happiness. (If you're not convinced, consider the corollary: if you are a shut-in, who never leaves home, has no hobbies and doesn't interact socially with people, your chances at either love or happiness or both are greatly restricted.)
Money is a very good way to facilitate these opportunities and experiences.
That's a very important point, imo. This was one of the main points of my original post. I.e. how can love and friendship replace money if money-spending is a condition for the social interactions that lead to love and friendship in the first place.
You may consider that there are public venues where people can interact without spending any money, but how many people avoid such venues precisely because of the class-status of at least some of the people present? Private venues, then, are informally regulated according to various status-markings, such that people feel more comfortable in certain venues because of some level of elitism or exclusivity defined by art, the cultural competencies of clientele, their clothing, etc.
This is starting to sound like Pierre Bourdieu on Distinction, symbolic capital, etc. The fact that people are upwardly mobile, i.e. looking to improve their current economic situation, leads them typically to avoid becoming friends or lovers with someone who appears not to hold the potential for attaining more money and/or higher status than the seeker presently feels they themselves possesses or have to potential to achieve.
The exception would be people who feel overwhelmingly blessed and privileged to the point that they feel that they have room to invest in someone with less potential than themselves. However, this seems to usually involve some kind of selectivity that is like a "purchase" of traits that cannot be directly translated into economic prosperity, such as more marginal forms of beauty or knowledge. Of course, these traits do tend to help people in economic attainment in many cases - but, for example, someone who makes plenty of money but is somewhat lacking in physical attractiveness may be able to win a more attractive partner than they would if they looked the same but had a lower salary. Is this a form of prostitution is the question, imo.
If such a thing as true love/friendship that is its own reward, then other forms of prosperity may fade in terms of interest or marginal utility. Someone who has found true love might find out that the type of car they drive comes to seem less relevant. On the other hand, if someone is afraid of losing love if they fail to maintain a certain image of youth, fashion, status, etc. - they may actually become more concerned about maintain their material status out of fear of losing love/friendship of the people they covet. This is probably a combination of insecurity and the expectation that friendships and love-relationships fail all the time and are, therefore, less dependable than material possessions.
