What's new with Chodosh - Facts on the ground | Why are people so lenient about a Din in the Torah?

Why do we rely on leniency these day when the Heter was due to שעת הדחק and we don’t have a shortage of food? If the Heter is based on Safek, nowadays the Safek is verifiable and can’t be relied upon If a store has information posted that it’s not Yoshon – there’s no Safek at all – what do people rely on? Why are people making on Stam Cholov which is maybe a Safek Derabbanan and not on this? If a person needed to eat because of פיקוח נפש and it was a question of הקל הקל תחלה should he eat Chodosh or drink Stam Cholov? People spend a lot of money and time checking vegtables for bugs which the obligation to check is Derabanan but blatantly eat Chodosh – why? Why does everyone spends thousands of dollars on computer check of a sefer Torah and here it’s easy to access the information and for free? Why are Chasidim so lenient – How does a story from the Baal Shem Tov uproot Halacha – even if it’s true we go with halacha not stories – we can uproot all the Torah if it’s controlled by stories not Halacha? Chassidim specifically love to quote Chasam Sofer “חדש אסור מן התורה” – when it comes to any slight deviance of Minhag or even culture – and חדש itself they don’t care about?
