Other than slight annoyance when things are hard to open, it's better. You can be sure no one stuck their dick in it, smeared a booger, or put anything harmful or anything else on or in it. Stuff also keeps longer, as long as you don't break the seal most stuff stays good for a long time.

Sure, if you are not experiencing the symptoms of medical conditions. Especially the conditions that led you to be opening the bottle in the first place, that's when it's especially insulting on top of the additional pain/fatigue the situation generates.
It's not even that I don't like seals. I love the caps and covers on the tins and bottles and jars of food in my kitchen. I even love recyclable ziplock bags, and there are flimsy takeaway containers out there that are literally watertight. I just don't like seals that are poorly made. There are products with usable seals out there, I know this first-hand. I've used them. I use them everyday.
Even then, not everything we consume has to be Fort Knox just because someone tainted a product intentionally or accidentally in the past. There are product recalls for various problems everyday and yet I've avoided getting ill from my groceries my entire life. I'm fine with buying my bread in a paper bag, I don't need them to start using hermetically sealed boxes with padlocks.
And honestly, there are so many points in the production lines of most things where someone has the opportunity to stick their dick in something, that I just can't dedicate the energy to entertaining that possibility on a daily basis. I also can no more verify that the last burger I ate was made by someone who washed their hands, any more than I can verify that the tomatoes I'm buying to make ketchup for homemade burgers weren't grown using human faeces and picked by slaves. And I say this as someone who has some immunity issues: There are just too many vectors for various kinds of contamination than you can imagine, let alone reasonably safeguard against - you have to pick and choose to battle the most likely to occur or kill you. I do not battle the possibility of penis in my products. I just don't have that kind of time.
We have the technology. This situation literally doesn't need to exist for anyone ever. And yet it's clearly common as fuck.
