Throw your cell phone, laptop, tablet and computer in the trash.
If you absolutely must talk to someone, do it face-to-face. In an emergency, get one of those el-cheapo phones and some minutes at Wal*Mart. Pay for them with cash. Wipe the fingerprints off it and throw it away every few days.
Otherwise write paper letters. They aren't opening all of those.
Make all your purchases in cash. No credit cards, no checks, No Paypal.
You get your picture taken dozens to hundreds of times every day. Wear a disguise. Something simple, just a stick-on mustache, dark sunglasses and a Red Man ball cap.
Stop filing tax returns. Adopt an alias. Stay away from all g'mint ops. No Vets hospitals.
Live in a city which is large enough to be anonymous. Vegas would be good.
You can run and you can hide.
They're still looking for Hoffa.
