If you have an 80 bit object, convert it to a 64 bit object, then convert it back to an 80 bit object, and you expect to drop zero bits, of course you'll run into problems. Posits can't fix these problems. Desktop graphics cards intentionally ignore IEEE 754 rules if it allows them to squeeze out a little bit of performance. (or die space, or power consumption depending on the application) If the bad guy is drawn half a pixel out of position or if his shirt is slightly the wrong shade of red, nobody cares. But if your graphics card draws at 72 frames per second and your competitor's cards draws at 73, every publication is going to say their card is better than yours. Posits won't fix this either. These problems you point out aren't technical problems, they're institutional ones. IMHO it's generally a bad idea to try to fix institutional problems with technical solutions, but I went try to stop you from attempting it.
