No, it’s not remotely. It is pointing out that you are engaging in the fallacy of special pleading. Something is only free if it has no out of pocked expenses for the user. Both email and postal mail have costs to the user. The consumer must pay for the service of Internet (or possibly cell phone service) to get emails. Thus that is part of the cost, even if they don’t pay a fee for every piece of mail.
It’s exactly the sort of thing that you do when you claim that free healthcare isn’t free, since taxes would increase. You’re not actually being good with your own political philosophy by claiming that email is free. Because then anything provided by tax money is also free.
The funny thing is, I expect very much that the costs of email is lower. So you could still make your point. But you insist on not admitting fault, and thus opening yourself up to this sort of response.
That said, your argument is flawed in that it mistakes the purpose of a postal service as to send information, when that is but one of its purposes. It also sends physical items, aka goods. And that latter part is more and more important as more and more business move to the same online ecosystem that email uses. It’s been a godsend during this pandemic crisis, keeping a large part of economy functioning while we stay at home.
And it’s doing so better than the commercial entities who try to handle the same job. The costs tend to be about the same (or even more expensive for the commercial entity), but the commercial services often have to depend on the government one to handle the last mile in order for that to work. All the while the law prevents the USPS from having savings or investing money that would be used for retirement to get better returns, unlike a private company which can do both.
To summarize, email may be superior for sending messages, but it can’t handle packages. And, in an economy that is increasingly national and global instead of local, sending packages is essential. And the USPS does it better than any commercial service. Hence it is still vital to the economy of our country.
Ifssaying that is political, then so is your attempt to discredit the service and make it seem outdated. Personally, I just care that the USPS makes things better for everyone, both in convenience and economically.
Until we have Star Trek style replicators, simply sending information will not be enough to replace postal services.
