My experience is the opposite.
It's more like go in on Saturday, try to find a pair in my size only to find they have 32" waist and 36" waist but ran out of 34" waist yesterday. I go to a different shop and they have 34" waist but only in extra short leg version with fashionable holes all over them, meanwhile 3 overly enthusiastic helpers have asked if I need any help with finding something they don't have any of. I'm already fed up by now and wanting to go home. I try a third shop and have to stand waiting for 10 minutes to try on the pair I miraculously found in my size, only to find the cut is weird and I don't like them. Go home disappointed, having wasted a few hours of my weekend driving into town and walking around, along with being charged a fiver for the privilege of parking my car for 2 hours. Resign myself to trying again next week.
Or I could go on Levis.com, order 5 or 6 pairs that I might like, receive them a day or two later, try them on at my leisure, send back any I don't like in the pre-paid returns material they give you by dropping it off at the Collect+ locker that's a 2 minute walk from my house, as I when I have a spare 5 minutes to do so in the next 90 days of their returns window. (But, given I know which Levis I like and which fit from last time I bought some, I can skip the entire 'buy loads and send back the ones I don't like stage entirely in this particular case)
I find shopping online massively preferable to shopping in person for most stuff - less of my free time is wasted trekking around shops that may or may not have what I want and as long as you pick your retailers sensibly, enough have reasonable returns policies.
Different things suit different people but the very fact this is even a proposal would suggest far more people are finding they'd rather do everything from the convenience of their own home these days than visiting their nearest high street.
