Per EPA for (however long) the tank cap has an intake air valve. If it's ancient it might get stuck open but otherwise it lets in just the air to displace the fuel.
That air does have whatever moisture amount the environment dictates. It could be an excessive amount. On the other hand it might not be, many people including myself have ran E10 for years and while we don't think it's better, it is still manageable.
Yes you may need to replace fuel lines or a carb diaphragm every 8 years or so, and watch that your fuel for smaller engines isn't aging past a couple months.
It is annoying that we've come to this, but I have not needed fuel stabilizer once, rather I just mix only the amount I'll need (a gallon at a time) and at end of season for seasonal equipment, run the engine to empty the fuel out.
It is more damaging to small engines because they aren't built to the same high (warranty) standards as automotive engines, but things like a fuel line replacement or carb rebuild or gaskets and diaphragm, yeah you have to plan on replacing them. Just don't make the mistake of assuming the whole piece of equipment is shot if all it needs is a carb cleaning, gaskets, and diaphragm. The latter is about $3 and 5 minutes time to replace.
Ultimately, you play the hand you are given. No sense in getting upset about the EPA because they aren't going away.
