you can own a foreign business and use both elite and ltr visa. Every single elite member my age is a business owner including myself.
Ltr visa you can legally work for foreign company under certain categories, and elite will say you can as well.. Technically you can't, but even the government said they won't track you down unless they have specific reasons.
The only "missing category" is for people who do not meet Thailand requirements of "have money". I do agree some of the ltr requirements were unneedingly difficult that exclude people unnecessarly, but it's there and might get better.
This what the government wants. They don't believe it's a missing opportunity.
