People want Reddit, people want FB and Insta. Do they pay for those? I’m not saying those are good or realistic models to follow but I think the scale of your product needs to be taken into account with your statement. ie landing millions of users can forgive the lack of a business plan _at that scale_ whereas a SAAS platform targeting B2B customers should probably require your statement to be true.
People aren't the customers of Reddit/Facebook, they're the product, that's why social media has such negative effect on mental health, the users aren't a concern beyond how many minutes they dump in for advertisers to pay for.
The advertisers are.

yeah, if your business plan lands millions of users you better have more than $40k ready to fund it. Since most people don't have that at hand it's actually a really problematic plan, because you've got to be able to secure the funding for it right when it starts to hit, if you don't you're done, if you do you might have to do it by giving up too much control, if you won't then you're done.
