Unfortunately, things can get quite messy when expert advice gets conflated with inventory management. And most shops struggling to survive against online doesn't make that better at at all. We really need to find some middle ground where foot-on-the-ground shop continue to exist, but not as an antithesis to online but as an extension. For bikes (of the pedal-pushing variety), there's now a market for what is effectively billed by the hour costumer-consulting regarding size fitting. I could easily imagine that getting transformed into foot-on-the-ground presence of online distributors, with neither income stream able to pay three full bill alone but working out in combination.
You're right, the inventory management part gets tricky. On the other hand they claim to only have inventory they trust and promote. So it becomes a question of "Do I trust this influencer's opinion?"
I've seen modern direct-to-consumer brands use the approach you mention. Their revenue stream is instagram ads and online retail, but they also have physical shops in bougie locations where you can go browse and talk to their [sales] staff. They only rep 1 brand which can be an issue.
Personally I've had good luck with specialist stores. You have to go in with a satisficing instead of maximizing mentality and it works great. The average on offer is about 10x better than the average you find online. (because inventory & space are expensive)

Doesn't matter if it's about size and fit. But I guess that's a problem that is very specific to human powered bikes, where an inexperienced rider can make wildly wrong choices based on just trying a few options (some of the best fits could take a year of regular riding for getting used to). There are lots of online shops in that field that make Amazon pale in both price and inventory depth (e.g. literally hundreds of different bar tapes, probably thousands if you count colors separately), I wonder if there could be an upmark percentage that would be acceptable to both retailers/post-retailers and customers for substituting the package delivery hassle with store pickup. Conventional retail competing with that choice is hopeless in a market consisting of nerd hobbyists. The old guard always thinks that customers only buy online because it's so much cheaper, but choice makes at least as much difference.
I suspect that the seemingly obvious hybrid distribution simply hasn't been done yet at scale because the legalities of customer protection require one party to be on the hook when things don't go so well and the online side of the equally wants to get rid of that so desperately that they wouldn't be interested in any arrangement that wouldn't provide for that and the retailer side is fully aware that they would never get a slice of the pie big enough to make up for those risks.
