I am not sure if 'unlimited, on-demand sex' could be considered a basic human need as I have sexual anhedonia alongside other types of anhedonia and I am barely able enjoy it. You simply get used to this even if it's depressing, just like with other things in your life. I wonder if I wouldn't want to kill myself if I didn't have anhendonia... I will never know. Also, the goverment in my country is actively trying to make prostitution illegal, so having money to spend wouldn't matter either.
And yes, even if you have little money you still can spend a small amount of it on recreational activities as a homeless person. I had a gaming laptop the whole time and I played with it on public libraries (free electricity) to attempt to make the whole ordeal less depressive, and it did make my life better. The laptop costs money, but it's a one time thing and it stays with you as long as it doesn't break, so it's not the same thing at all.
Honestly, I don't really think people would had enough money to do what you suggested even if they weren't poor, specially on SS where most people struggle financially. Your solution is not very realistic, that's what I am saying.
You're expanding my statements to apply to many different situations that they don't apply to, when I've stated over and over that the situation I'm addressing is when someone proclaims that sex is their number one goal in life and the most important thing to them. If my posts were vague and unclear, then sure, you could just come up with hypotheticals for various situations, but I'm extremely clear that this is the only situation I'm addressing. If someone says that sex (just sex, not deep intimacy, love, or a relationship in any way, but just sex) is the absolute MOST important goal to them, the thing they want most to achieve above all other things, it is illogical that they would then be willing to pursue and spend money on various recreational activities *before* sex. They're clearly prioritizing those other activities first. That's obviously fine, but if they continue to state that sex is their number one goal and claim they can't achieve it, it means there's some other reason, *besides* the aspect of cost, that they aren't going to a sex worker.
There are plenty of other reasons, such as stigma, nerves about the first interaction, simply wanting it to be someone they meet by chance, etc, but this conversation goes nowhere when none of that is acknowledged. If someone doesn't want to go to a sex worker, that's obviously completely fine. But over and over, this conversation happens and the person who's claiming they can't access sex *isn't* saying they don't want to see a sex worker; they're just proclaiming that access to sex is impossible for them. This is the entire premise of my posts; my posts obviously DON'T apply to extreme situations like homelessness, I'm responding to the people who say that sex is their absolute highest desire, that they have no way to achieve it, and are at the same time pursuing other desires first. I'm saying that in that situation, seeing a sex worker is a way to achieve sex that bypasses the issues of physical appearance, social status, etc. that can be barriers to achieving sex otherwise.
It's not completely devoid of all barriers, because yes, it costs money. But anyone who is deeply impoverished already likely doesn't have money for dates, transportation, clothes, or many things that are helpful or necessary to achieve sex otherwise. The common statement with this conversation is that things like physical appearance and social status are what stop people from being able to get sex; I've never seen anyone say that their number one goal is to get sex, they have a great physique, are great in social situations, and have everything else they need, but the one thing that is stopping them is lack of money. Seeing a sex worker bypasses nearly everything you need in regular social situations, and the single thing you need to do is pay.
