I'm with you, but the vaccine is like 32$ per dose, so 64$ total and completely blows out of the water all of those in their effectiveness. A lot of those drugs also have quite the side effects, I don't think it's clear to me they are more/less safe than vaccines.
And then there's the issue that look how many choices there are? And it's still pretty unclear which of all of those is most efficient and how efficient exactly are they, so if you get Covid what do you do? Take 35 different cheap and maybe slightly effective drugs together in a big cocktail?
The other issue is they all mention requiring early treatment, but tests and other ways to detect Covid early aren't readily available or cheap, so do you now take this giant cocktail of mixed drugs every time you have a cold in case it turns out to be early onset Covid? Do you just take them all on a regular basis as a preventative?
My current personal assessment is that the vaccine still absolutely outshines all of these in every single dimension. I really wouldn't say we've found an actual cheap treatment that is truly effective and realistically easy to implement quite yet. While it does seem that we've found multiple vaccines that are.
P.S.: Side note, that website you link is the most random thing, they don't divulge anything about who they are, what's funding it, what's behind them, I only found an FAQ saying: Trust us we're a bunch of smart PHDs not looking for fame and remaining anonymous. Now I'll give them the benefit of the doubt that they are truly well meaning expert in the know, but I also find it sketchy as hell, why not actually disclose who you are and how the operation is financed?
