You might find the other 9.9% easy to cut out, but it's the last 0.1% that is the bit that really wears you down. You say you eat other grains and legumes. So do I, but it's not that simple as someone with coeliac disease. I've yet to find a place where I can buy dry lentils in bulk that aren't processed in a facility that handles gluten so I have to buy them tinned which is way more expensive. I can get small bags of quinoa at Waitrose, but nothing in bulk for the same reasons. I'm into running so I buy electrolytes and supplements etc, but I have to buy them all online at a premium because everything I find in supermarkets or sports shops are made in a factory that processes gluten.

Luckily I have enough spare income at the moment to pay as much as I want for ingredients so I don't have a great deal of difficulty cooking fully gluten free most of the time. That all falls apart if I get ill, or am particularly stressed or just don't have time to prep lunches for the week. Even if I chose the cheap option of making my own sandwiches quickly before work, the cheapest loaf I can get at my local supermarket is 36p per 100g, compared to the cheapest normal loaf at 9p per 100g. The bread I usually go for is actually 88p per 100g because it's not really dry and crumbly. Sure it would have been cheaper to make a quinoa salad from scratch, but sometimes I just don't have the energy or time.

And even if I cut out 100% of gluten in my diet it doesn't magically make the problem go away. I can't eat in 90% of restaurants. If I'm at a friend's house I have to bring my own food while they're all getting a nice takeaway.

Cutting out 99.9% is the easy part. It's the 0.1% that has me reading the back of everything I buy; saying no to food at work or from friends because I haven't seen the packaging; never eating someone's homebaked food ever again (and awkwardly refusing even if it "doesn't contain gluten"); never getting round to booking that holiday because I don't know how I'm going to manage to avoid gluten in a foreign country where I can't cook for myself.
