Even hosting friends at your house incurs a cost, however small: for extra food and drinks. Literally every human activity incurs a cost. Well, you can become a Hikikomori, so your only expenses will be electircity and internet.
If you equate a good time with spending money it is always going to cost money. I do almost nothing with my time that cost money, I have a lot of perks paid by work that I do not use because I just see no use for them.
I'm not equaling anything with anything. I'm pointing out the reality to people claiming that "oh it's so easy to maintain any kind of hobbies and/or social life without spending a penny"
> I do almost nothing with my time that cost money
