Also true, but as someone who ran my own asn and space for 5 years, it can be a pain when it doesn’t work. Spent a good chunk of time making sure my space showed as Ireland, not us or Germany. Netflix, Disney+ and others all didn’t like me to start… but there are ways of fixing it.
It's not that hard. Look up what your local internet registry requires (ARIN, RIPE, APNIC, AfriNIC, LACNIC) to allocate an ASN and allocate a /24 or at least approve a transfer of a /24. Typically you should have a location with two internet providers that will propagate your prefixes via BGP to their peers and transit. Find companies willing to accept your money so you can meet the requirements, also find someone with a /24 to transfer to you assuming your registry doesn't have any.
Yep, this - the process isn't hard but it is tedious. W/ ARIN you also have some waiting to do - and must register as a business and pay that registration fee.
