I also root for monopoly busting, but worry that the travel and real estate industries are relatively easy sectors to target compared to the real monopoly companies (Meta/Twitter/TikTok, Amazon, Apple's walled garden). The power in those older industries is fairly distributed across a large number of companies and individuals, so coordinated lobbying is more challenging (even for Realtor Association). Shadowy cabals are easier to maintain when fewer people have real power (you don't even need the shadows or the cabals!). Furthermore, customer's interact with them fairly infrequently.

Compare the older industries to TikTok's recently demonstrated ability to shutdown access to congressional representatives on topics other than keeping regulator's and legislator's hands off the company. The power difference is obvious regardless of how you feel about the debate around TikTok.

Social media platforms are definitely not a monopoly. A new one springs up every few years and the next generation wants to be on a shiny new platform which doesn't have their parents. Myspace -> FB -> WhatsApp -> Snap -> Tiktok -> ...

FB survived so long only because they could acquire Insta and WA. One thing regulators have to do would be to not let incumbents acquire new upstarts. And looking at the current trends, that is far more likely than not (see Adobe + Figma).
