I don't see how it would be easier necessarily as I assume the rules in countries that make it hard to buy some cards as a visitor, would apply to companies selling esims too.

Many android phones offer dual SIM trays which shouldn't even preclude the ability to offer esim.

The regulations don't preclude selling SIM cards to people who live in a hotel. It's just that the incumbents don't care enough about travellers to make it easy because they are too small of a market.

With esim, the barrier to entry is lower -- a virtual mobile network operator could target travellers and make it easy to get a temporary SIM, without having to first build up a huge distribution network for physical SIM cards.

It would even make it possible to get a temporary SIM card from a different country, which would circumvent some of the restrictive regulations (eg. Germany requires registration with address for phones registered in Germany but allows you to use an "anonymous" phone registered in another country.)

This has been my experience - it's much easier to find a traveller-focused eSIM package - they just show up as options when you land somewhere.
