I have used such service for some 20 years. It's called sneakemail.com (paid service) It's great. I have several hundreds of addresses, and only a dozen or so I had to close because they started to produce spam. Interesting enough most of them pretty renowned businesses from the days when privacy policies did not exist.
The nasty thing is that an increasing number of businesses block such onetime addresses (there are lists on github). Linux Foundation a prominent offender. They send me their marketing BS, but I cannot unsubscribe because "my address is invalid". My bank is a recent addition. They still send me email, but several functions in my online banking don't work because I have to "confirm" my email first and the one they have on file and works is not accepted.
I hope such services would be widely used that no serious business can afford to block them.
I have also been a sneakemail user for probably 15 years and have accumulated over a thousand addresses. Two years ago I switched to using a catchall .com domain because the sneakemail domains are blocked so frequently. Domains from other services like 10minutemail.com and fakenamegenerator.com tend to
be blocked, too. Plus addressing is also hit or miss — sometimes a system will let you sign up with a plus addressed email but other parts of the system will reject it (ahem, banks).
15 years ago, a catchall email domain was unthinkable since spammers would try dictionaries of words against a domain in hopes of finding legitimate email addresses. However, this no longer seems to be a trend.

From a businesses point of view it's a tricky one because disposable addresses are widely used when someone's trying to abuse a service. Personally I find blocking email providers pretty gross, but you can see how someone facing a torrent of malicious traffic from accounts associated with disposable addresses could get annoyed enough to just block them.
Unlikely they would know provided you use realistic names/canaries and dont have dozens or hundreds of friends also using your domain with the same websites.
If the day comes that people can't use their own domains then companies will effectively cut off the very communication with their customers and prospects they desired to have in the first place.
I've been a spamgourmet user and fan for... must be 20 years now. Great service. I haven't run into any blockers like you describe, but I've long dreaded the day when I do.
+1! Sneakemail is fantastic and well worth the money.
I use it since 2007 but avoided mentioning it anywhere because of fear it could be banned by spammers; some already do. They probably will have to change their domain name one day.
