Bc the range of commercial offerings is so diverse and cost effective. Once upon a time, probably longer ago then 10, if you had a specific need that couldn’t be solved by cheap shared hosting, then self hosting at home might make sense if you planned to do all the patching, backups, hardware cycling, monitoring, etc yourself and didn’t care about network redundancy. Today it is nice for a certain variety of hobbyist for whom home data center is their thing. Otherwise host it somewhere competent.
Sure you can work around it with dynamic DNS but that's a hassle and hassles like that are what make it infeasible.
